Support of old git version in pass application

[Vascom]

Hi all.

I want to ask is pass able work with git versions without "-C" functional now?
Because of that problem in pass 1.7.3 it was removed from EPEL7 repo
and not available in RHEL/CentOS 7.

Please look at https://bugzilla.redhat.com/show_bug.cgi?id=1639806
