S/390: Disassemble 31-bit binaries with "zarch" opcode set by default 

Currently the disassembler for s390 (by default) assumes that a 31-bit
binary was compiled in "ESA" mode -- and then only disassembles a
limited opcode set.  The change upgrades the default to the full "zarch"
opcode set even for 31-bit binaries.

	* s390-dis.c (init_disasm): Default to full 'zarch' opcode
	availability even for 31-bit programs.
