device: dumpstate: expand f2fs dump script

Browse Source 
With the recent changes in partition mapping, multiple f2fs partitions
exists and is not fixed to specific dm-x. To address this, update the
script to dynamically locate f2fs partitions.

New log:
------ F2FS - fragmentation (/vendor/bin/sh -c for d in $(ls /proc/fs/f2fs/); ...
