soc/amd/picasso/Makefile.inc: force an error if PSPBTLDR_FILE is not set

Currently, if PSPBTLDR_FILE is empty, the md5sum will hang forever on
stdin, leading to the appearance of a hung script. This is
confusing.

There's no option to md5sum to say "you must use this file", so instead,
use dd with if to ensure we at least get an error if the file is not found.

Not optimal, but better than what we have now.
