since kde-runtime was merged into kde-workspace some checks definitions are
duplicated in config-runtime headers thus it is removed.
missing function and header checks were added, most of which also missing in
kde-runtime and kde-workspace so that is by no means mistake made during the
merge.
the check for libkstat for Solaris is actually done via /dev/kstat existence
check from ksysguardd/Solaris/Solaris.cmake.
