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
