Title: Add <setup> tag to IBus engine meta-data

This is needed for Debian and Ubuntu.

"ibus-sunpinyin" Debian package installs "ibus-setup-sunpinyin" to /usr/lib/ibus-sunpinyin/ ; "ibus-setup" cannot find the setup program automatically and thus render "Preferences" button gray.

Add explicit can solve this problem.
