analysis/functions: Do not import glib::translate for special functions

Special functions either do not need any translation imports at all
(ref/unref, copy/free), or their trait implementation adds imports as
appropriate.

Note that certain `copy` functions need `mut_override`, which also comes
from the translation module.
