microsoft/clc: increase test-timeout for clc_compiler_test

This test takes almost 30 seconds here, which makes it time out randomly when I'm doing something else on my computer.

This also happens quite frequently on CI. So let's quadruple the timeout, from the detail 30 seconds to 120 seconds. This should still let us catch proper hangs, while allow for somewhat congested runners to still have a chance of passing.

This isn't the ideal way of fixing this, though. Ideally, we should subdivide this test into several smaller tests. But that's a larger change, so let's put this band-aid on for now.
