[PATCH 2/2] perf test: Skip test_arm_callgraph_fp.sh if unwinding isn't built in

[James Clark]

Even though this is a frame pointer unwind test, it's testing that a
frame pointer stack can be augmented correctly with a partial
Dwarf unwind. So add a feature check so that this test skips instead of
fails if Dwarf unwinding isn't present.
