readrom: print the usual PRG-RAM size if available
If 'has_persistent_memory' has been set on the ROM header, then we must
print it even if bytes 8/10 was never set by the header. In fact, the
vast majority of ROM files don't have these bytes set but they report a
true value for 'has_persistent_memory'. Hence, assume the usual PRG-RAM
size in these cases, which is (I hope) the correct one in all cases.
