tests: Create test for virCommandDoAsyncIO

Browse Source 
This is just a basic test, so we don't break virCommand in the
future. A "Hello world\n" string is written to commanhelper,
which copies input to stdout and stderr where we read it from.
Then the read strings are compared with expected values.
