tests: drop `(py3 !)` output matching predicates

Presumably these were paired with `(no-py3 !)` at one point, but now they were
unconditionally true.

test-check-code.t required a couple of `(glob)` markers on the changed lines in
test-lfs-serve-access.t, because of the `$LOCALIP` usage on those lines.  Not
sure how those lines slipped through the checks previously.
