Test files created by test_create*() tests will stay in the $efivarfs_mount directory until next reboot.

When the tester tries to run this efivarfs test again on the same system, the immutable characteristics in that directory with those previously generated files will cause some "Permission denied" noises and a false-positive test result to the test_create_read() test.

Remove those test files in the end of each test to solve this issue.
