[project][qemu] Ignore IOErrors in close

Closing a broken pipe when a test times out raises an IOError which
has the effect of masking the Timeout error indicating that the
test took too long. This prevents us from distinguishing tests that
take too long from tests that are flaky or fail for other reasons.

Test: run test that causes timeout
Bug: None
