Fix use of target_link_libraries with an IMPORTED target.

cmTarget::MaybeInvalidatePropertyCache only invalidates the cache
for properties matching "IMPORTED_*".

We need to append in the tll implementation to
the IMPORTED_LINK_INTERFACE_LIBRARIES_NOCONFIG property, because
that is what is read by cmTarget::ComputeImportInfo in the case
of no config.

Apparently there is some problem with multi-config generators
with this patch.
