Add erofs-util API support for overlaybd

salvete commented 5 months ago

What this PR does / why we need it:

Previously, erofs-utils was integrated into overlaybd by using the mkfs.erofs executable file. It's not optimial since raw data needs to be dumped first and output data needs to be write into overlaybd then.

This adds EROFS API support for overlaybd.
