[PATCH] More simple udev rules handling

[Riccardo Magliocchetti]

There are a lot of issues reported on Debian BTS of not handled
cameras or more in general issues with udev. Mine is not recognized
too while it should because there should be a generic rule for
ptp cameras.

Looking in /etc/udev/rules.d and in /lib/udev/rules.d i haven't
found any link to gphoto2 rules so maybe _that_ is why it's
not working. So my idea of fix is just makes thing more simple.

I've done these changes:
- force link of udev rules in every case and remove the old one
  if exists
- one user reports that moving the rule from 025 to 090 fixed the
  issue for him, i have no idea if that could make a difference,
  so move the rule later to 90 since the other scripts here are
  not using levels starting from zero.
  In upstream documentation they use 90 too.
