forthstrap: avoid unaligned accesses

Trying to compile OpenBIOS for SPARC32 on a SPARC machine, I get a
SIGBUS within forthstrap, more precisely accessing reloc_table in
load_dictionary. This table is not aligned because the dictionnary
head as a size which is not a multiple of 4.

This is due to the file QEMU,tcx.bin which is being encoded, and which
has a size which is not a multiple of 4. Fix that by adding some padding
after the encoded data.
