[S390] Fix disassembly of RX_URRD, SI_URD & PC-relative instructions.

The instructions with format RX_URRD and SI_URD and instructions
with a PC relative operand are not disassembled correctly.
For RX_URRD and SI_URD instructions find_insn sets opfrag to code[0].
The mask byte of these two formats is 0x00. table->opfrag will never
be identical to (opfrag & opmask) and no matching instruction will
be found. Set the mask byte to 0xff to actually check byte 0 against
the table.
For PC relative instructions the (unsigned) offset value needs to be
casted to an signed integer so that negative branch offsets are
handled correctly.
