[PATCHv2] selftests/efivarfs: clean up test files from test_create*()

[PATCHv2] selftests/efivarfs: clean up test files from test_create*()

[po-hsu.lin]

Test files created by test_create*() tests will stay in the
$efivarfs_mount directory unless the system was rebooted.

When the tester tries to run this efivarfs test again on the same
system, the immutable characteristics in that directory will cause some
"Operation not permitted" noises and a false-positve test result to the
test_create_read() test.

    --------------------
    running test_create
    --------------------
    ./efivarfs.sh: line 59: /sys/firmware/efi/efivars/test_create-210be57c-9849-4fc7-a635-e6382d1aec27: Operation not permitted
      [PASS]
    --------------------
    running test_create_empty
    --------------------
    ./efivarfs.sh: line 78: /sys/firmware/efi/efivars/test_create_empty-210be57c-9849-4fc7-a635-e6382d1aec27: Operation not permitted
     [PASS]
    --------------------
    running test_create_read
    --------------------
    open(O_WRONLY): Operation not permitted
     [FAIL]
    --------------------

Create a file_cleanup() to remove those test files in the end of each
test to solve this issue.

Also, use this function to replace the existing file removal code.
