perf test: add test for BPF metadata collection
This is an end-to-end test for the PERF_RECORD_BPF_METADATA support.
It adds a new "bpf_metadata_perf_version" variable to perf's BPF programs,
so that when they are loaded, there will be at least one BPF program with
some metadata to parse. The test invokes "perf record" in a way that loads
one of those BPF programs, and then sifts through the output to find its
BPF metadata.
