perf c2c: Fix remote HITM detection for Skylake

Skylake introduced new mem_remote bit in union perf_mem_data_src [1].
It applies to any other memory level to express Remote unknown level, as
is reported by Skylake.

Adding this extra check to c2c_decode_stats to properly decode remote
HITMs on Skylake.
