[PULL 04/10] tests/functional: Speed up the avr_mega2560 test

[Thomas Huth <thuth@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

We can simply check for the expected pattern on the console,
no need to wait for two seconds here to search for the pattern
in the log at the end.

While we're at it, also remove the obsolete "timeout" variable
from this test.
