gobjectIntrospection: use absolute path for cairo GIR

Cairo does not provide its own GObject bindinds so they are provided
by gobject-introspection package. Unfortunately, this means that if we
want to use the absolute path, we need gi to depend on cairo, which
increases the closure size from 41M to 56M. We will probably want
to split the typelib into a separate output.

Closes: #34080
