selftests/landlock: Add layout1.umount_sandboxer tests

Browse source

Check that a domain is not tied to the executable file that created it.
For instance, that could happen if a Landlock domain took a reference to
a struct path.

Move global path names to common.h and replace copy_binary() with a more
generic copy_file() helper.

Test coverage for security/landlock is 92.7% of 1133 lines according to
gcc/gcov-14.
