runtime: remove crash_cgo_test CgoRaceSignal timeout

The test had a 5 second timeout. Running the test on a Darwin system
sometimes took less than 5 seconds but often took up to 8 seconds.
We don't need a timeout anyhow. Instead, use testenv.Command to
run the program, which uses the test timeout.

Fixes #59807
