Report mincore.check_file_mmap as SKIP instead of FAIL if the underlying
filesystem lacks support of O_TMPFILE or fallocate since such failures
are not really related to mincore functionality.

Add a test suite for the mincore() syscall. It tests most of its use
cases as well as its interface.
Tests implemented:
- basic interface test
- behavior on anonymous mappings
- behavior on anonymous mappings with huge tlb pages
- file-backed mapping with a regular file
- file-backed mapping with a tmpfs file
