[PATCH] tests/acceptance: Print expected message on wait_for_console_pattern

[Wainer dos Santos Moschetta <wainersm@redhat.com>]

For the sake of improve debuggability of tests which use the
wait_for_console_pattern(), this changed the _console_interaction() so that
the expected message is printed if the test fail.

While I was testing  "[PATCH v2 2/2] tests/acceptance: Test ast2600 machine"
I could not clearly determine which of the called wait_for_console_pattern()
was failing. So this patch improves debuggability in such as situations.
