[PATCH 11/13] tests: change "cat && chmod +x" to use "write_hook"

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Refactor various test code to use the "write_hook()" helper. Let's
indent this code and add it to "test_expect_success" while we're at
it.

As in a preceding commit some of this code drops the explicit "mkdir
-p", but as noted we'll be having the "write_hook" wrapper handle that
soon anyway.
