net/http: remove arbitrary timeout in TestServerHijackGetsBackgroundByte_big

This test fails with "timeout" once per couple of months.
It may be that the arbitrary timeout is too short,
or it may be that the test is detecting a real bug
(perhaps a deadlock) and reporting it without sufficient
information to debug.

Either way, the arbitrary timeout is doing only harm:
either it is too short, or it is preventing us from getting
a useful goroutine dump when the test inevitably times out.

Fixes #35498 (hopefully).
