udev-extraconf: drop mount.sh

There were two reasons for maintaining Toradex specific mount.sh:
- The first, we wanted to handle Toradex specific boot partitions for
  eMMC modules in /etc/fstab..
- The second was we wanted to mount medias on /media instead of
  /run/media.

But this has at least two drawbacks:
- It causes we might miss the future updates in OE's mount.sh.
- Another more serious drawback is it will lead to a knew issue:
  https://bugzilla.yoctoproject.org/show_bug.cgi?id=12644

For the first issue, we can fix it by introducing another udev rule for
boot partitions, to create a symbolic link:
/boot -> /media/BOOT-PARTITION-MOUNTPOINT

For the second issue, we can fix it by using MOUNT_BASE variable to
change mount base from /run/media to /media.
