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

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.
