selftests: add mincore() tests

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
