perf test: Record only user callchains on the "Check Arm64 callgraphs are complete in fp mode" test
The testcase 'Check Arm64 callgraphs are complete in fp mode' wants to
see the following output:
610 leaf
62f parent
648 main
However, without excluding kernel callchains, the output might look like:
ffffc2ff40ef1b5c arch_local_irq_enable
ffffc2ff419d032c __schedule
ffffc2ff419d06c0 schedule
ffffc2ff40e4da30 do_notify_resume
ffffc2ff40e421b0 work_pending
610 leaf
62f parent
648 main
Adding '--user-callchains' leaves only the wanted symbols in the chain.
