fix(installer): set XDG_DATA_DIRS for vala builds and add missing deps

Export XDG_DATA_DIRS in build_invercargill_json and build_usm functions
to ensure GObject Introspection and Vala can find .gir and .vapi files
from bundled and system libraries.

Also add json-glib-devel, libarchive-devel, and libgee-devel to dnf
dependencies, and remove git which is not a build dependency.
