Adrian Hunter d9efc1d252 perf scripts python: export-to-postgresql.py: Add has_calls column to comms table
Now that a thread's current comm is exported, it shows up in the call graph
and call tree even if it has no calls. That can happen because the calls
are recorded against the main thread's initial comm.

Add a table column to make it easy for the exported-sql-viewer.py script to
select only comms with calls.

Committer testing:
