Link lib/libc/c063 tests to the build.

[jilles]

Summary

Some files lack required #include <sys/stat.h>.

The faccessat test fails because it tries to use AT_SYMLINK_NOFOLLOW with
faccessat(), which is not specified by POSIX.1-2008.

Test Plan

buildworld and installworld, kyua test in /usr/tests/lib/libc/c063.

Please put these if #ifdef FreeBSD #endif blocks so I don't forget to upstream them to NetBSD..

"The faccessat test fails because it tries to use AT_SYMLINK_NOFOLLOW with
faccessat(), which is not specified by POSIX.1-2008."

The testcase should either be #ifdef NetBSD'ed out, or have a block like this added to it:

#ifdef __FreeBSD__
atf_tc_expect_fail("Depends on non-standard behavior not mentioned in POSIX.1-2008");
#endif

Apply changes requested by ngie. 'kyua test' in c063/ is happy now.
