[mojo-edk] Fix some multiprocess test expectations

Some of the shared buffer tests were waiting for child processes
to respond to "quit" messages with an "ok" before exiting, but
delivery of that message can race with child process exit, leading
to MojoWait failures.

This extra synchronization step is unnecessary, so this CL removes
it.
