ipv4: ip_tunnel: Replace strcpy use with strscpy

Use of strcpy is decpreated, replaces the use of strcpy with strscpy as
recommended.

strscpy was chosen as it requires a NUL terminated non-padded string,
which is the case here.

I am aware there is an explicit bounds check above the second instance,
however using strscpy protects against buffer overflows in any future
code, and there is no good reason I can see to not use it.

I have also replaced the scrscpy above that had 3 params with the
version using 2 params. These are functionally equivalent, but it is
cleaner to have both using 2 params.
