When parsing udev data, skip lines that don't start with `E:`.
Lines prefixed with `E:` represent device properties, as documented in
udevadm(8).

Set the `--path.udev.data` flag to point to the udev fixture, and update the
output fixture with
```console
$ ./end-to-end-test.sh -u
```

Now that we read some data from `/run/udev/data`, add the corresponding
fixtures and update the expected test results accordingly.

Instead of hard-coding the path to `/run/udev/data`, intoduce a
`--path.udev.data` flag that defaults to that value.

Add labels to the `node_disk_info` metric extracted from udev, such as `model`,
`path`, `revision`, `serial` and `wwn`.
Also add a few metrics related to filesystem and device mapper, which are also
extracted from udev information.

Problem: In 0b50eb7294 the usage of the
threshold variables was adjusted. The values had been switched as well
resulting in reversed thresholds after the commit above. Warnings now
have a smaller threshold than critical alerts.
Solution: Adjust thresholds to reflect that warnings should be alerted
on before critical alerts.

Use unix.ByteSliceToString to convert Utsname []byte fields to strings.
This also allows to drop the bytesToString helper which serves the same
purpose and matches ByteSliceToString's implementation.
