Brandon Williams 1fd1a919ce t5550: use write_script to generate post-update hook
The post-update hooks created in t5550-http-fetch-dumb.sh is missing the
"!#/bin/sh" line which can cause issues with portability.  Instead
create the hook using the 'write_script' function which includes the
proper "#!" line.
