calib-workflow.sh: PV-contributor veto for the cosmics in async

With CALIB_ASYNC_EXTRACTCOSMICS=1 the cosmics matcher gets
--pv-contributor-sources $VERTEXING_SOURCES when the primary vertexing
runs, as the time series gets $TRACK_SOURCES: the TPC part of a vertex
contributor is no cosmic leg. COSMICS_PV_VETO=0 switches it off,
COSMICS_PV_SOURCES overrides the sources. The option ignores sources
without TPC, so the vertexing sources are passed as they are (help text).

Checked in print mode (veto on / off, without ITS: TPC-TOF) and on 4 PbPb
TFs with the full vertexing source list: the same seeds rejected as with
the 4 ITS-TPC sources that have contributors there.
