Subject: [PATCH 3/4] futex: Remove unused or redundant includes

Since 82af7aca ("Removal of FUTEX_FD"), some includes related to file
operations aren't needed anymore. More investigation around the includes
showed that a lot of includes aren't required for compilation, possible
due to redundant includes. Simplify the code by removing unused
includes.

To test this code, I compiled with different configurations (x86_64,
i386, with x32 ABI supported enabled/disabled), and ran futex selftests.
