libtracker-extract: Add extractor modules manager.

This manager parses a directory of keyfiles, describing rules
for matches, the modules aren't preloaded on initialization,
instead they are loaded lazily as needed.

This supersedes the module loading within
src/tracker-extract/tracker-extract.c, and will be used
as a replacement in following commits. The specific/generic
matching there can be replaced by rules at different priorities
calling the same module.
