[ostree] tests/admin-test.sh: add #!/bin/sh

[Colin Walters <walters src gnome org>]

commit 35f412c86af1767feec65290de0ca7aa3e57dccd
Author: Simon McVittie <smcv debian org>
Date:   Sat Mar 19 17:54:38 2016 +0000

    tests/admin-test.sh: add #!/bin/sh
    
    This is executable and appears to be intended to be executed directly,
    so it should have a #! line.
