qmp drive-mirror : set big timeout

Browse Source 
drive-mirror is doing lseek on source image before starting, and this can take a lot of time for big nfs volume
during this time, qmp socket is hanging
http://lists.nongnu.org/archive/html/qemu-devel/2015-05/msg01838.html
so we need to setup a big timeout

qemu devs are currently working to fix this
