[BOLT] Spawn buildid-list perf job at perf2bolt start. NFC (#185865)

Browse Source 
Launch this perf job with the others at the beginning of the aggregation
process.

Extracting buildid-list from perf data is not a costly process, so it
can be performed by default. This provides a distinct advantage when
this dataset is required in other perf2bolt stages as well.

Please see PR #171144.
