Use the current erofs-utils testsuite, the following tests seems skipped incorrectly.

[Error 22] Invalid argument
SKIP: erofs/008
[Error 22] Invalid argument
SKIP: erofs/009
[Error 22] Invalid argument
SKIP: erofs/010
[Error 22] Invalid argument
SKIP: erofs/011

[Error 22] Invalid argument
SKIP: erofs/017
[Error 22] Invalid argument
SKIP: erofs/018

And the kernel message shows:
[  116.477816] erofs: source is unsupported
...

$ sudo make check
