Cleber Rosa 61f7450662 tests/boot_linux_console: increase timeout
When running on very low powered environments, some tests may time out
causing false negatives.  As a conservative change, and for
considering that human time (investigating false negatives) is worth
more than some extra machine cycles (and time), let's increase the
overall timeout.
