fix(dracut-init.sh): handle decompress with `--sysroot`

Remove `$dracutsysrootdir` from the file path passed to the decompress command,
otherwise the path is wrong and the file is not decompressed in the temporary
directory where the initramfs is being built.

E.g.:

```
dracut[I]: *** Including module: i18n ***
gzip: /var/tmp/dracut.6Iqygd/initramfs/.snapshots/12/snapshot/usr/share/kbd/keymaps/i386/include/euro1.map.gz: No such file or directory
gzip: /var/tmp/dracut.6Iqygd/initramfs/.snapshots/12/snapshot/usr/share/kbd/keymaps/i386/qwerty/us.map.gz: No such file or directory
gzip: /var/tmp/dracut.6Iqygd/initramfs/.snapshots/12/snapshot/usr/share/kbd/keymaps/xkb/us.map.gz: No such file or directory
```
