Subject: fix(dracut): properly detect kernel version with --sysroot
Both `uname -r` and `cd /lib/modules` do not give the proper kernel version of
the sysroot directory.
E.g. of the wrong behavior:
```
$ dracut -f --sysroot /srv/tw --no-kernel test.img
realpath: /srv/tw/lib/modules/6.19.6-1-default: No such file or directory
$ uname -r
6.19.6-1-default
$ ls -l /srv/tw/usr/lib/modules
total 0
drwxr-xr-x. 1 root root 630 Mar 25 16:30 6.19.8-1-default
```
Follow-up for 2b2debd7947b7d5a357c1a89691a75dfd3565747
