Silence 'make checkbashisms'

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.
