tomoyo: use better patterns for procfs in learning mode

Commit 08ae2487 ("tomoyo: automatically use patterns for several
situations in learning mode") replaced only $PID part of procfs pathname
with \$ pattern. But it turned out that we need to also replace $TID part
and $FD part to make this functionality useful for e.g. /bin/lsof .
