os: deflake TestFdReadRace by increasing timeout

This timeout will never be reached if the test passes, so it doesn't
much matter how long it is. The test is t.Parallel so on a slow system
1 second may occasionally not be enough, although on my laptop the
test takes about 0.02 seconds.

Fixes #34431
