The same utility method is already present in two different test
files, so let's consolidate it into a single utility function.

Note to self: it would be useful if wait_for_console_pattern could 
return the read lines. Example of use: a test case waits the kernel to 
boot - if succeed - then it can check if SMP topology is expected by 
parsing the console lines.

Regardless, this change looks good to me.
