[build] Allow GITVERSION to be specified as an environment variable

Browse Source 
When using GitHub Actions with a job container that does not have the
git tools installed, the actions/checkout step will download a
snapshot instead of performing a git clone, and will therefore not
create a .git directory.  Allow the GITVERSION variable to be
specified externally, so that the test suite logs can still display
the commit of the build being tested.
