scripts/gtm900[bp]-ffs-clean: remove some more wrong files
An earlier version of GTM900-B firmware has been found in the wild that
still has MFW&BMI layers included (producing files under /mmi), as well as
enlarged /pcm/L[DMR]N files. These files are wrong for FreeCalypso fw
and thus need to be cleaned out.
