blkparse: Handle cgroup information
Since Linux kernel commit 35fe6d763229 "block: use standard blktrace API
to output cgroup info for debug notes" the kernel can pass
__BLK_TA_CGROUP flag in the action field of generated events. blkparse
does not count with this and so it will get confused by such events and
either ignore them or misreport them. Teach blkparse how to properly
process events with __BLK_TA_CGROUP flag.
