gst-plugins: fixed pattern for meta package dependencies.

gst-plugins: fixed pattern for meta package dependencies.

This fixes package name matching so that gst-plugins-*-meta
packages include all the plugin ones. The current matching
implementation doesn't make meta packages depend on gst-plugins
with 'locale' and 'dev' in their names (f.e. gstfbdevsink).
Also use INC_PR for gstremer-plugins as requested on ML.
