emubd: Dropped lfs_emubd_cksum/bdcksum

Browse Source 
One of these was missed during the crc -> cksum rename, so it wouldn't
have even linked correctly. Rather than fixing it I'm just going to drop
these functions.

At some point they were useful for debugging, but with emubd's disk
mirroring and dbgblock.py, it's both easier and more reliable to
find checksums with external scripts.
