[PULL 5/7] tests/acceptance: Refactor and improve reporting in linux_ssh_mips_malta.py

[Cleber Rosa <crosa@redhat.com>]

From: Aleksandar Markovic <amarkovic@wavecomp.com>

This patch restructures code organization around the test case
executions. At the same time, rather than outputing a cryptic message:

FAIL: True not found in [False],

the following will be reported too, if the command output does not meet
specified expectations:

'lspci -d 11ab:4620' output doesn't contain the word 'GT-64120'
