Only ibus.o needs the D-Bus and xkbcommon flags, so give them the same
per-object scoping as the popup and XIM objects. The docker targets used
-B, which recursive makes inherit: the daemon was linked three times and
the live tests built twice per docker-check. gtk/Makefile repeated the
module-directory check and cache refresh in install and uninstall.
The GTK IM module only emitted the commit signal when the key was
eaten (r != 0). But when a non-matching key is pressed mid-composition
the engine commits the pending preedit and returns eaten=0 so the raw
key passes through, sending a commit string with eaten=0. GTK dropped
it, silently losing the composed text (e.g. Hangul "ㅇ" + "?" yielded
only "?").
Commit whenever a commit string is present, matching the wayland, ibus
and xim frontends.
