rootfs: support EROFS filesystem

Browse Source 
For kata containers, rootfs is used in the read-only way.
EROFS can noticably decrease metadata overhead.

On the basis of supporting the EROFS file system, it supports using the config parameter to switch the file system used by rootfs.

Fixes: #6063
