Updated automount-usb.sh to look for a particular parition label "NAS"

This aims to fix the issue where the udev rule spits out a random partition in sda that might not contribute too the partition that has the games.

For example lets say we have a USB drive that has 
sda
sda1 - 30m
sda2 - 200gb

since the udev rule will detect sda being added it will always forward the first partition and update the samba share config with sda1 instead of sda2

at first, the idea was to sort the partitions by size but it was finicky. In the end I settled on looking for a label as it was more straightforward
