test: adjust test-push-race.t timeout's to overall test timeout

The generic `tests/testlib/wait-on-file` mechanism scale its timeout with the
value of `HGTEST_TIMEOUT`, the `delaypush.py` in `test-push-race.t` is not doing
this, and we have been seeing more and more timeout from loaded CI worker
lately.

Adding this timeout scaling should help with that.

 Test cases where there are race condition between two clients pushing to the same repository
 ============================================================================================
 
 This file tests cases where two clients push to a server at the same time. The
 "raced" client is done preparing it push bundle when the "racing" client
 perform its push. The "raced" client starts its actual push after the "racing"
 client push is fully complete.
 
 A set of extension and shell functions ensures this scheduling.
