Reapply "[libc] Return errno from OFD failure paths in fcntl." (#166658) (#166846) 
The previous implementation in #166252 (rolled back in #166658) caused
buildbot failures due to a bug in an added test. The modified
`UseAfterClose` did not pass a `struct flock` value to `fcntl`:


2d51705941/libc/test/src/fcntl/fcntl_test.cpp (L175)

Which ASAN caught and errored in the `fcntl` implementation when the
unspecified argument was accessed:
