fix(dracut-functions.sh): check_kernel_module should follow dracutsysrootdir

ryncsn · aafeijoo-suse · commit 6c42d378abe5 · 2022-12-21T17:07:46.000+01:00
check_kernel_module calls modprobe and tries to dry-run a module load to
check if a module is available. modprobe supports `-d` to specify a
rootdir, so just pass dracutsysrootdir to it to make it work as expected
when building initramfs for another rootfs.
