temphack: using __k_condvar_area_end instead of __data_end

Temphack until section groups has been implemented.

Section groups will allow a developer to setup a group of sections that
belongs together in such a way that they should form a continous area in
code or memory, and where the start and end of such group should have
known linker symbols defined.
