We need to be able pass both the bundle path and the pid file
paths to conmon from ocid.
The former is mandatory when creating an OCI container:
https://github.com/opencontainers/runtime-spec/blob/master/runtime.md#create
And it makes sense to provide a full path for the latter as the
current hardcoded relative path may lead to errors if e.g. the
runtime chdir() before creating the PID file.
In both cases we try to create default reasonable values when
they are left empty by the caller.

conmon uses getopt() even if it's a glib based application,
and therefore could use the much more modern and flexible
GOptionContext mechanism. Fixes#89
