Subject: [PATCH] Handle non-integer udev version strings

CentOS 8's systemd reports this for `udevadm --version`:

```
[vagrant@localhost ~]$ udevadm --version
239 (239-44.el8)
[vagrant@localhost ~]$ udevadm --version | awk '{print $1;}'
239
[vagrant@localhost ~]$ udevadm --version | sed -e 's/\s.*$//'
239
```

Using sed rather than awk to get the first token out, since it is
already declared as a dependency in the dracut spec.

This works fine on fully integral versions, e.g. on Fedora 33
```
$ udevadm --version | sed -e 's/\s.*$//'
246
```
