Fix compilation error on systems without SuiteSparse installed
Issue was caused by declaring class PerThreadContext with some
members of choldmod-specific types. This class in only used from
an #ifndef CERES_NO_SUITESPARSE block and solved compilation error
by simply wrapping PerThreadContext with the same #ifndef block.
