Subject: [PATCH v4 24/31] fs/resctrl: Add type define for PERF_PKG files

Creation of the default info file for monitor resources requires
an RFTYPE_RES_ define and for fflags_from_resource() to map from
the RDT_RESOURCE_PERF_PKG resource to the RFTYPE_RES_PERF_PKG value.

Add the define and case in fflags_from_resource().
