Enhanced Read-Only File System (EROFS) has been included in Linux
kernel, many Linux distributions, buildroot and Android AOSP for
a while. Plus, nowadays, it's known that EROFS has been commercially
used by several Android vendors for their system partitions.
This patch adds support for detecting EROFS filesystem to libblkid.
Since util-linux/util-linux@cd129b7 introduced blkid_probe_set_block_size
function to report filesystem block size, TWRP is using blkid 2.25.0, which
means blkid_probe_set_block_size wasn't supported and required, so remove
the blkszbits judgement and blkid_probe_set_block_size for fixing building.
Test: Add erofs mount point to twrp.flags, build and boot

Now TWRP can recognize the EROFS filesystem perfectly after setting fs in twrp.flags

for android-10
This will support updating the ramdisk to a different
compression format and co-exist with magisk.
We are also cleaning up and removing non android-10
api makefile actions.
We are also moving twrp repacking to its own class. We
check the new ramdisk format and if it's different
we have magisk compress using the new ramdisk format.

Break libblkid into 4 libraries: libblkid, libuuid, libutil-linux and libfdisk.
This should help in later patch updates.
