usbmount: stop using blkid, use udev environment variables instead
The blkid binary is not any longer installed when libblkid from util-linux is selected. udev has a builtin blkid command though and already detects all values that we are interested in. Change the usbmount script to use the environment variables set by udev instead of calling blkid directly.

The usbmount package automatically mounts USB mass storage devices
|

when they are plugged in, and unmounts them when they are removed.

udev can provide all the values that usbmount determined using the
|
||||
blkid binary. This patch drops use of blkid in favor of using the
|
||||
environment variables set by udev. Thus it removes the dependency
|
||||
on blkid from usbmount.
