Make SuiteSparse partitioning detection more robust

FindSuiteSparse skipped the METIS lookup if METIS_FOUND was defined.
Other find modules, such as the one shipped by COLMAP, define this
variable without providing the METIS::METIS target. The Partition
component was then reported as missing even though CHOLMOD supports it.

Search for METIS whenever its target is unavailable and report why a
required Partition component is missing.
