Based on the iso8859-2 compose, and a bug report by Vladimír Marek,
override the en_US.UTF-8 use of <dead_caron> <u> to enter »ǔ« instead
to enter »ů«, and likewise for the majuscule, for the Czech locale.
This evidently is the norm for Czech keyboards.
Fixes bz#81875.
The XI18N_OBJS and XLC_LOCALE.pre files are empty, as they are for
several other locales. That may require an update.
