Fix some issues with icu for dict tool

The dict tool can be run during the build, therefore
copy just in case icu data file to tool application path,
so it does not require installation and can
run no matter if it is a prefix non prefix build.

Guard for webengine_system_icu since there is no icu file
in that case.

Remove awesome looking genex from examples.
