CMake: Add a special skip genex marker when walking libs

Browse Source 
Useful to annotate certain linking expressions that need to be skipped
for inclusion in prl file generation. E.g. $<TARGET_OBJECTS>
expressions that represent propagated object libraries, which are
handled by the rcc_objects walk lib code path, and thus need to end up
in prl RCC_OBJECTS section, instead of the
QMAKE_PRL_LIBS_FOR_CMAKE one.
