s390/bpf: Fix branch shortening during codegen pass
commit 1511df6f5e9ef32826f20db2ee81f8527154dc14 upstream.
EMIT6_PCREL() macro assumes that the previous pass generated 6 bytes
of code, which is not the case if branch shortening took place. Fix by
using jit->prg, like all the other EMIT6_PCREL_*() macros.
