osmo-depcheck.py: set dependency hashes on command line
Right now, osmo-depcheck.py (from osmo-ci.git) always uses the versions of the dependencies that are specified in configure.ac of the Osmocom project that is being tested.
pespin was just using the script and wanted to check if a project builds against a specific commit of a dependency. He said, it would be nice to have something like:
./osmo-depcheck.py -b osmo-msc:7231edb7321a238851387479df0ee16d6c936de0[libosmocore:aa98c481fa7888e2bcd9d5c9ae1993744ee47f33]
(so after the project:hash, add  with a list of dependencies)
