[PATCH] BBB: sd_setup.sh: Change /bin/bash -> /bin/sh to solely adhere to POSIX shell constructs

[Ed Sutter]

Jarielle,
Did you try running the script with that change?
I applied the patch, then tried running it and it failed.
Apparently 'echo' in sh is different than 'echo' in bash, at least it is for my system.
Let me know.
I had to remove the -e from the echo lines for it to work on my ubuntu14.04 system.
You wanna test that and resubmit the patch or should I do it?
Ed
