Camera no longer supplies the hostname to the dhcp server

[olivluca]

I was using an old 0.4.x version and I just updated to the latest one (0.5.5).
Now the camera doesn't supply the correct hostname to the dhcp server, that's because in the script /home/yi-hack/script/wifidhcp.sh reads it from /tmp/sd/yi-hack/etc/hostname instead of from /home/yi-hack/etc/hostname (where the hostname is saved from the web interface).
That was done in commit 9cf96db, why?
