bcachefs: thread_with_file: allow creation of readonly files
Create a new run_thread_with_stdout function that opens a file in
O_RDONLY mode so that the kernel can write things to userspace but
userspace cannot write to the kernel. This will be used to convey xfs
health event information to userspace.
