perf tools: Correct SNOOPX field offset
perf_event.h has macros that define the field offsets in the data_src bitmask in perf records. The SNOOPX and REMOTE offsets were both 37. These are distinct fields, and the bitfield layout in perf_mem_data_src confirms that SNOOPX should be at offset 38. Committer notes: This was extracted from a larger patch that also contained kernel changes.
