t: fix &&-chaining issues around setup which might fail

Many tests have an initial setup step that might fail based
on whether earlier tests in the script have succeeded or
not. Using a trick like "|| true" breaks the &&-chain,
missing earlier failures (and fooling --chain-lint).

We can use test_might_fail in some cases, which is correct
and makes the intent more obvious. We can also use
test_unconfig for unsetting config (and which is more
robust, as well).

The case in t9500 is an oddball. It wants to run cmd1 _or_
cmd2, and does it like:

cmd1 || cmd2 &&
other_stuff

It's not wrong in this case, but it's a bad habit to get
into, because it breaks the &&-chain if used anywhere except
at the beginning of the test (and we use the correct
solution here, putting it inside a block for precedence).
