Subject: perf annotate s390: Fix perf annotate error -95 (4.10 regression)

From: Christian Borntraeger <borntraeger@de.ibm.com>

commit e77852b32d6d4430c68c38aaf73efe5650fa25af upstream.

since 4.10 perf annotate exits on s390 with an "unknown error -95".
Turns out that commit 786c1b51844d ("perf annotate: Start supporting
cross arch annotation") added a hard requirement for architecture
support when objdump is used but only provided x86 and arm support.
Meanwhile power was added so lets add s390 as well.

While at it make sure to implement the branch and jump types.
