Subject: [PATCH] Tip-toe around rpmfiFN() thin ice in fsm

Any pointer gotten from rpmfiFN() is only valid until the next
rpmfiFN() call, and here the path can end up inside plugins which
may have their own reasons for calling rpmfiFN(). At which point
the dest we passed would be invalid. strdup() it to appease ASAN,
but this needs a saner solution really.
