Reviewed by Jean-Yves Avenard.

The stall-resume.py script inside css/selectors/media/support/ will cause 
requests made
to block until a POST unblocks loading. This causes problems with Range 
requests as multiple
range requests may be issued, succeed, but block at the 4k mark. Once the POST 
is issued,
it becomes a race as to which request will become unblocked.

Modify stall-resume.py so that the POST command will unblock _all_ requests for 
a limited
time (5s). Also update the request path so that a cancelled request is detected 
and causes
the server to bail out early, reducing concurrent blocked requests.

Un-skip this test and two other related ones that are passing on WPT.fyi.
