selftests/landlock: Simplify ruleset creation and enforcement in fs_test

Browse Source

* Add enforce_fs() for defining and enforcing a ruleset in one step
* In some places, dropped "ASSERT_LE(0, fd)" checks after
  create_ruleset() call -- create_ruleset() already checks that.
* In some places, rename "file_fd" to "fd" if it is not needed to
  disambiguate any more.
