libsysprof: propagate devices to processinfo

Browse Source 
We need access to this from the process info but can share the instance.
It sucks to walk the hashtable here, but the alternative is to make these
recursive so that we can check a parent mount namespace.

Until then, take the hit and iterate all the pids to populate them with
the additional device.
