Use socat exit status to determine if the socket is usable

Browse Source 
Instead of checking, if *any* qutebrowser process is running (which may or may not have an IPC socket where we expect it), simply launch a new instance  *if socat fails*. 
Which it does, if: 
* the socket file doesn't exist (qutebrowser simply not running), or
* the socket isn't connectable (qutebrowser crashed, left orphaned socket)
 
Also put new instances into background, so the script behaves a bit more consistently. (Else it *sometimes* blocks and *sometimes doesn't*, when run.)
