test2600: remove special case handling for USE_ALARM_TIMEOUT

This was originally added to handle platforms that supported only 1
second granularity in connect timeouts, but after some recent changes
the test currently permafails on several Windows platforms.

The need for this special-case was removed in commit 8627416, which
increased the connect timeout in all cases to well above 1 second.

Fixes #11767
Closes #11849
