Log a single error message when the udev data directory (`/run/udev/data` by
default) is unreadable, and then don't try to get device properties out of it.
Also lower the log level from error to debug when we can't parse the udev files
properly, since these messages would be sent every time the node exporter gets
scraped.

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.
