net/http: deflake tests in full mode after t.Parallel additions
https://golang.org/cl/18087 added a bunch of t.Parallel calls, which
aren't compatible with the afterTest func. But in short mode, afterTest
is a no-op. To keep all.bash (short mode) fast, conditionally set
t.Parallel when in short mode, but keep it unset for compatibility with
afterFunc otherwise.
Fixes #13804
