Fixing Broxygen indexing confusion for plugins.

Browse source 
Because plugins register their script directories with the BROPATH,
Broxygen stripped them out from plugin script paths it was indexing.
That then led to multiple plugins ending up with the same script
paths, triggering warnings about duplicates.

I fixed this by checking if a script comes out of a plugin. If so, it
gets an artifcial index prefix "<plugin-name>:", followed by the
script's relative path inside the plugin's top-level directory. For
example, "/opt/bro/lib/bro/plugins/Bro_Netmap/scripts/init.bro" now
turns into "Bro::Netmap:scripts/init.bro" for Broxygen purposes
(whereas it used to be just "init.bro").

Addresses BIT-1663.

(Can't think of a good way to add a test for this unfortunately.)
