Subject: [PATCH 34/53] perf record: Use OPT_BOOLEAN_SET for buildid cache related options

'perf record' knows whether buildid cache is enabled (via
--no-no-buildid-cache) deliberately. Buildid cache can be turned off
in some situations.

Output switching support needs this feature to turn off buildid cache
by default.
