s390/bpf: Support BPF_PROBE_MEM32
BPF_PROBE_MEM32 is a new mode for LDX, ST and STX instructions. The JIT
is supposed to add the start address of the kernel arena mapping to the
%dst register, and use a probing variant of the respective memory
access.
Reuse the existing probing infrastructure for that. Put the arena
address into the literal pool, load it into %r1 and use that as an
index register. Do not clear any registers in ex_handler_bpf() for
failing ST and STX instructions.
