cmd/dist: pass a -test.timeout option to a host test

For a host test we build the test using "go test -c" and then run the
test binary. A test binary run in this way has no default timeout.
This CL gives it a timeout of 5 minutes, scaled for the target.
We can adjust the timeout if necessary.

For #52998
