Update MuonEventTPCnv reference files after !31114

Since !31114 (merged) was merged into 21.3, the MuonEventTPCnv_20.1.7.2 unit test has been failing due to the fact that the reference file was not updated after the TPCnv bug was fixed.

This merge request also backports a fix from master to allow TPCnv unit test reference files to be read from cvmfs.

FYI @ssnyder and @nkoehler

added alsoTargeting:21.9 bugfix labels
