* Build libpfm as a dependency to allow collection of perf counters
This commit builds libpfm using rules_foreign_cc and lets the default
build of the benchmark library support perf counter collection without
needing additional work from users.
Tested with a custom target:
```
bazel run \
--override_repository=com_github_google_benchmark=/home/raghu/benchmark \
-c opt :test-bench -- "--benchmark_perf_counters=INSTRUCTIONS,CYCLES"
Using profile: local
