Subject: [PATCH] dracut-module-setup.sh: use "*" to expend array as string

upstream: fedora
resolves: bz2003832
conflict: none

commit da3ad9cbdaa332ed9384799e4b3198b9e55c5cd3

    dracut-module-setup.sh: use "*" to expend array as string

    As suggested by:
    https://github.com/koalaman/shellcheck/wiki/SC2199
    The array is not quoted here but implicitly concatenate still happens,
    could be harmless but shellcheck complains about it so fix it.
