gtk3: backport an upsteam GI syntax fix

Backport upstream's fix for a syntax error (missing colon) in the
annotations.

https://git.gnome.org/browse/gtk+/commit/?id=f703ea65995f4c8bd5c7e1c554a36d5ca835067d

This doesn't address Alexpux/MINGW-packages#845, but it's probably worth
having in our builds.
