Problem with Recognizing Dirtags

Was getting the following error when using ccdb2_test.xml:

======= directory tag mismatch found =======
== package being checked = gluex_root_analysis
== prerequisite package = halld_recon
== prerequisite's home directory = /home/marki/gluex_top_ccdb2/halld_recon/halld_recon^ccdb2
== no directory tag in home directory name

but there is a directory tag in the home directory name. The algorithm to recognize the dirtag in the home directory path spec was failing if there was no version number field in the path spec. For this version case that was true for halld_recon since it was cloned from the git repository.

Made the fix in build scripts. See this pull request.
