4ee218a2d2 pgrep/pkill: fix -x to also match comm field 
When running `pgrep -x example` against a process `/bin/example --arg`,
BusyBox fails to match, while GNU pgrep succeeds. The reason is that the
comparison is done only against the full argv[0] rather than comm. This
patch changes pgrep -x to also try /proc/[pid]/comm for exact matching.
