Enable mCBM 2022 real data L1 reco for CI
Re-enable the L1 reco now that the fix in !1087 (merged) brought back the processing time to reasonable values (~600-700s for first TS which is in-spill, ~2400s for first 20 TS which have mix of in and out of spill). \
MR also include a quick fix for some bug found recently in legacy STS unpacker config, this should not impact anything else so I dared to attach it
My feeling is that this does NOT absolutely need to be backported to the release as anyway the mCBM analysis in the current master is not matching 100% what the mCBM team uses.
