Subject: [PATCH] Add EROFS to file system check list

This commit will add EROFS Filesystem mount support

Since Huawei announced the new file system EROFS and successfully
merged into mainline. More and more OEMs switch the ext4 filesystem
to EROFS filesystem for system/vendor/odm/product partitions like
Oplus (OPPO / Realme / OnePlus).

Test: Import the latest fstab from system, build and boot. EROFS-based
partions like system and vendor partitions were sucessfully mounted.

Notes: Although I tried to change 'ext4' to 'erofs' for correct partition
in twrp.flags, but it was still recognized as 'ext4'. So you can just copy
the line related erofs partitions from recovery.fstab and TWRP will failed
to recognize the line in twrp.flags, and then skip this line, so the issue
was solved.
