libbpf: Fix invalid return address register in s390
commit 7244eb669397f309c3d014264823cdc9cb3f8e6b upstream.
There is currently an invalid register mapping in the s390 return
address register. As the manual[1] states, the return address can be
found at r14. In bpf_tracing.h, the s390 registers were named
gprs(general purpose registers). This commit fixes the problem by
correcting the mistyped mapping.
