CI: add xfstests

Add xfstests into CI for overlayfs, it will work as Github Actions.

Currently not all test cases can be run, only about half of `generic/*`
for the Fuse Overlay FS, some test cases are expected to fail due to
missing function implementation, little are unexpected due to potential
bugs which will be investigated laterly.
