cppcms: really depend on wchar

In commit f8993ebb34823b301ea2bf4f1f57495ec29b906b ("cppcms: needs
wchar support even without icu"), Peter wanted to move the wchar
dependency from the ICU sub-option of cppcms to the main cppcms option
itself. However, for some reason it didn't do the entire change, and
the commit was lacking:

 * Removing the wchar dependency from BR2_PACKAGE_CPPCMS_ICU

 * Adding the wchar dependency to BR2_PACKAGE_CPPCMS.

It was only handling the two comments.

This should really fix:

and other similar build failures that are still occuring after
f8993ebb34823b301ea2bf4f1f57495ec29b906b has been applied.
