Commit d2bce6d03 added the 'make checkbashisms' target but did not
resolve all of the bashisms in the scripts. This commit doesn't
resolve them all either but it does fix up a few, and it excludes
the others so 'make checkstyle' no longer prints warnings. It's
a small step in the right direction.
* Dracut is Linux specific and itself depends on bash. Therefore
all dracut support scripts can be bash specific, update their
shebang accordingly.
* zed-functions.sh, zfs-import, zfs-mount, zfs-zed, smart
paxcheck.sh, make_gitrev.sh - these scripts were excuded from
the check until they can be updated and properly tested.
* zfsunlock - only whole values for sleep are allowed.
* vdev_id - removed unneeded locals; use && instead of -a.
* dkms.mkconf, dkms.postbuil - use || instead of -o.
