Gregory Szorc 276defc2a7 Bug 1393503 - Proper error handling for failure to find VCS tool; r=glandium,nalexander
``print()`` has no business being in library code like this. It was
a holdover from this code being copied from bootstrap. So remove it.

While we're here, replace the generic exception with a specific one.
We don't want to be swallowing bugs via ``except Exception``.
