Robustify process_SUITE:spawn_opt_max_heap_size/1

process_SUITE starts os_mon in init_per_suite/1. Therefore,
there may be occasional alarm info messages received. Make
sure that they are ignored and don't cause the test fail to
fail.

Also, get rid of the flush/0 function that discards all
messages in the message queue. Instead, be more selective
and only discard {error, ...} messages.
