mdb_copy() was dutifully checking the PATH for the mdb_copy executable,
then, if it didn't find it, blindly proceeding anyway and trying to run
a non-existent executable. This resulted in a cryptic error:
ERROR(<type 'exceptions.OSError'>): uncaught exception - [Errno 2] No
such file or directory
Add in an extra check that we actually find the executable and raise a
better human-readable exception if we don't.
