since find_package_handle_standard_args() is used and no status messages
are printed by the modules there is no reason to set <MODULE>_FIND_QUIETLY
variable (which should be prefixed with the actual module name, not upper
case)

neither the Plasma runner nor the applet actually used the QALCULATE_CFLAGS
variable meaning that if Qalculate was installed in non-standard prefix
the build was likely to fail, this fixes that problem by replacing it with
QALCULATE_INCLUDE_DIR which will be used in the build system for the applet
and runner.
also fixes a CMake deprecation warning about using obsolete UsePkgConfig
module.
