Add mkfifo{,at}(2) mode in mknod{,at}(2) as requested by POSIX

mknod with mode & S_IFIFO and dev=0 shall behave like mkfifo.

Update the documentation to reflect this state.

Add ATF tests.

This is an in-kernel implementation as typically user-space programs use
mkfifo(2) directly, however whenever there is need to bypass libc (like in
valgrind) then portable POSIX software calls the mknod syscall.

Revert defective O_SEARCH implementation committed by manu@ along with
the *at system calls on November 18th of last year. Reasons to revert
it include:
- it is incorrect in a whole variety of ways (but fortunately, one
of them is that the missing and improper permission checks have
no net effect);
- it was committed without review or discussion;
- core ruled that all the new O_* flags pertaining to the *at calls
needed to wait until their semantics could be clarified.

manu was asked to revert it on these grounds but has ignored the request.

I have left O_SEARCH defined and visible and made open() explicitly
ignore it. This way, most code that tries to use it will continue to
build and run. I've also arranged lib/libc/c063/t_o_search.c so that
the tests that make use of the O_SEARCH semantics will disappear until
O_SEARCH comes back, and fixed some mistakes and/or incorrect hacks
that were causing some of these to succeed despite the broken O_SEARCH
implementation.

Split the test cases where root/non-root makes a difference in two and mark
them apropriately. Exact permission semantics are still under discussion,
this will have to be cleaned up once that discussion is settled.
For now, one test cases fails.
