ibus-daemon: ignore standard component path if IBUS_COMPONENT_PATH is set

Don't load components from /usr/share/ibus/components if
IBUS_COMPONENT_PATH is set.  Currently the envvar is only useful
for testing and appending the standard path makes little sense.

Remove gnome-icon-theme-legacy dependency.

gtk_image_set_from_icon_name() accesses the icon_name only but
gtk_image_set_from_stock() can fallback the stock name to the real name.
E.g. "gtk-about.png" is the symlink of "help-about.png" and
"gtk-about.png" is included in gnome-icon-theme-legacy package in Fedora.
