main: doMount: call Setsid before starting logger

The logger should be in the new background session together
with the gocryptfs process.

Before:
	$ xfce4-terminal -x gocryptfs a b
	$ ps xao pid,ppid,pgid,sid,comm,args
	    PID    PPID    PGID     SID COMMAND         COMMAND
	 192272    1371  192272  192272 gocryptfs       /ssd2/jakob.donotbackup/go/bin/gocryptfs -fg -notifypid=192265 a b
	 192292  192272  192265  192265 logge <defunct> [logger] <defunct>

After:
	$ xfce4-terminal -x gocryptfs a b
	$ ps xao pid,ppid,pgid,sid,comm,args
	    PID    PPID    PGID     SID COMMAND         COMMAND
	 211714    1371  211714  211714 gocryptfs       /ssd2/jakob.donotbackup/go/bin/gocryptfs -fg -notifypid=211708 a b
	 211776  211714  211714  211714 logger          logger -t gocryptfs-211714-logger
