prime_numbers modules search and skip logic removes the module instead

intel_pstate testing script
The intel_pstate related testing script need root level privileges
when trying to access certain file for the successful execution of
the script.But this is not the case always like when using evaluation
only mode, which only require user level privilege.
This patch is to notify the user about the privilege the script
demands for the successful execution of the test.

A few changes improve the overall usability of the test:
* fix a hard-coded maximum frequency (3300),
* don't adjust the CPU frequency if only evaluating results,
* fix a comparison for multiple frequencies.
A symptom of that last issue looked like this:
./run.sh: line 107: [: too many arguments
./run.sh: line 110: 3099
3099
3100-3100: syntax error in expression (error token is \"3099
3100-3100\")
Because a check will count how many differente frequencies
there are among the CPUs of the system, and after they are
tallied another read is performed, which might produce
different results.

Cgroups are used for controlling the physical resource distribution
(memory, CPU, io, etc) and often are used as basic building blocks
for large distributed computing systems. Even small differences
in the actual behavior may lead to significant incidents.
The codebase is under the active development, which will unlikely
stop at any time soon. Also it's scattered over different kernel
subsystems, which makes regressions more probable.
Given that, the lack of any tests is crying.
This patch implements some basic tests for the memory controller,
as well as a minimal required framework. It doesn't pretend for a
very good coverage, but pretends to be a starting point.
Hopefully, any following significant changes will include corresponding
tests.
Tests for CPU and io controllers, as well as cgroup core
are next in the todo list.

Split normal memfd and hugetlbfs tests to improve the test reporting.
Remove run_fuse_test.sh and memfd_test from run_tests.sh and add them
to the Makefile.
Add memfd_test to TEST_GEN_PROGS to be run separately.
Rename run_tests.sh to run_hugetlbfs_test.sh
Add run_fuse_test.sh and run_hugetlbfs_test.sh to TEST_PROGS

When net test is skipped because of unmet dependencies and/or unsupported

with ratio=2 as the default mode to be able to invoke the test without
the "-r 2" argument from the common RUN_TESTS and EMIT_TESTS.

RUN_TESTS did. Common defines work with the run_tests.sh set as the

Kselftest framework builds and installs TEST_GEN_FILES and doesn't run
them via RUN_TESTS and include it in EMIT_TESTS. With this change the
new run_tests.sh runs the test after checking dependencies.
This change also adds Skip handling to return kselftest skip code when
test is skipped to clearly identify when the test is skipped instead of
