sanity.bbclass: modify check for shell

Due to the recently implemented update-alternatives for bash binary,
sanity checker may end up with a (false-positive) error such as:

Error, /bin/sh links to /bin/bash.bash, must be dash or bash

This patch modifies the test: presence of "/bash" or "/dash" in shell binary
name results in pass.
