test: add UV_TIMEOUT_MULTIPLIER environment var

Browse Source 
Add an environment variable that lets people running the test suite
specify a timeout multiplier. Useful when running the tests on slow
machines.

Some tests are timing sensitive. Relaxing test timeouts may be necessary
on slow or overloaded machines:
```bash
$ env UV_TEST_TIMEOUT_MULTIPLIER=2 ./out/Debug/run-tests # 10s instead of 5s
```
#### Run one test
The list of all tests is in `test/test-list.h`.
