libtracker-common: Use procfs psinfo instead of cmdline on Solaris
libtracker-common: Use space if the artist name is not known

This is to follow the following spec:
https://wiki.gnome.org/MediaArtStorageSpec#Identifiers

Space will be the fallback if the artist name is unknown.

Fixes GB#705834
vapi: Removed src/vapi/ which was required for very old versions of gio-2.0.vapi
