Andrei Borzenkov 1018e91dce mkimage: zero fill alignment space 
This did not cause real problem but is good for reproducible builds. I hit
it with recent bootinfoscript that displays embedded config; I was puzzled
by random garbage at the end.

Prezero memory buffer used to assemble core.img. This makes individual
memset redundant. Also ensure buffer is filled with zeroes in several other
places.

Also remove redundant zeroing code where we fill in the whole memory block
anyway.
