[PATCH 4/7] tests/acceptance: Sun4uMachine: Remove dependency to LinuxKernelTest

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

The Sun4uMachine class inherit from LinuxKernelTest to effectively only use
the KERNEL_COMMON_COMMAND_LINE attribute. This change remove that unneeded
dependency, making Sun4uMachine self-content.

I took the occasion to delint the code: the unused os import was
removed, imports were reordered, and the module has a docstring now.
