[PATCH for-11.0 11/15] tests/functional/aarch64/test_virt_gpu: Fix style issues

[Thomas Huth <thuth@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

Reshuffle the import statements according to the suggestions from pylint,
use lowercase letters for variable names, and drop some spaces that flake8
did not like.
