Fix Makefile to set TEST_GEN_PROGS instead of TEST_GEN_FILES to fix the problem. run_tests runs TEST_GEN_PROGS, TEST_CUSTOM_PROGS, and TEST_PROGS. TEST_GEN_FILES is for files generated by tests.

This prevents building against kernel headers from the build environment in scenarios where kernel headers are installed into a specific output directory (O=...).

This tests that: - no invalid flags can be specified - changing properties of a single mount works and leaves other mounts in the mount tree unchanged - changing a mount tre to read-only when one of the mounts has writers fails and leaves the whole mount tree unchanged - changing mount properties from multiple threads works - changing atime settings works - changing mount propagation works - changing the mount options of a mount tree where the individual mounts in the tree have different mount options only changes the flags that were requested to change - changing mount options from another mount namespace fails - changing mount options from another user namespace fails - idmapped mounts Note, the main test-suite for idmapped mounts is part of xfstests and is pretty huge. These tests here just make sure that the syscalls bits work correctly.
