6512bf0e - [libc] Migrate dirent/fcntl/sched/signal tests to ErrnoCheckingTest. (#158700)

[libc] Migrate dirent/fcntl/sched/signal tests to ErrnoCheckingTest. (#158700) Remove direct libc_errno.h inclusion and manipulation of libc_errno in various unit tests, instead relying on ErrnoCheckingTest machinery. This is the final mechanical change of migrating libc unit tests to ErrnoCheckingTest - after it, all the unit tests relying on ASSERT_ERRNO_* macro will be using ErrnoCheckingTest.h
