fix(i18n): handle keymap includes with `--sysroot`

The results of `find "${dracutsysrootdir}${kbddir}"/keymaps/ -type f -name "${INCL}*" -print0`
are directly passed to `findkeymap` containing the `$dracutsysrootdir` path,
which causes that `[[ -f $dracutsysrootdir$1 ]]` evaluates to false because the
same path is prepended again, and the following `find` fails because `MAPNAME`
has an absolute path.

E.g., with `dracutsysrootdir=/.snapshots/9/snapshot`, for `MAPNAME=us` the
`INCLUDES` of `MAP=/.snapshots/9/snapshot/usr/share/kbd/keymaps/i386/qwerty/us.map.gz`
will pass `/.snapshots/9/snapshot/usr/share/kbd/keymaps/i386/include/qwerty-layout.inc` to
`findkeymap`.

```
dracut[I]: *** Including module: i18n ***
find: warning: ‘-name’ matches against basenames only, but the given pattern contains a directory separator (‘/’), thus the expression will evaluate to false all the time.  Did you mean ‘-wholename’?
```
