I hit following building error randomly:

This is caused by tools/perf/util/intel-pt-decoder/Build that, it tries to
generate $(OUTPUT)util/intel-pt-decoder/inat-tables.c atomatically but
forget to ensure the existance of $(OUTPUT)util/intel-pt-decoder directory.
This patch fixes it by adding $(call rule_mkdir) like other similar rules.
