sanity.bbclass: check /bin/sh is dash or bash

The build would fail when /bin/sh links to ksh or csh, we only test dash
and bash AFAIK.

* When /bin/sh -> csh:
  $ bitbake quilt-native
$ bitbake quilt-native -cfetch
Illegal variable name.
Illegal variable name.
[snip]
uname: extra operand `2'
Try `uname --help' for more information.

* When /bin/sh -> ksh:
  If there are only a few tasks running, for example,
  "bitbake quilt-native", the build would be OK, but it would fail if we
  run "bitbake world" for a while, there would be a lot of "Broken pipe"
  errors:
Exception: CalledProcessError: Command
'cd /path/to/xx; find . -type d -print | tar -cf - -C /path/to/sysroot-destdir -p --files-from - --no-recursion | tar -xf - -C /path/to/xxx'
returned non-zero exit status 2 with output tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors
find: `standard output': Broken pipe
find: write error
