run: detect daemons when run via wrapper commands

The run script tries to detect when a daemon is being run in order to
shutdown other systemd unit files that clash. As implemented this
only works if the daemon name is the first argument. This won't be the
case if running via GDB or strace eg

  ./run strace -e trace=openat ./build/src/virtqemud

We need to check all argv to find which might be a daemon path/name.
