[PATCH for-11.0 08/15] tests/functional/x86_64/test_memlock: Silence pylint warnings

[Thomas Huth <thuth@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

Pylint complains about a missing "encoding" parameter for the open()
function here, and about a missing return statement in the "except"
block (which cannot happen since skipTest() never returns). Rework
the code a little bit to silence the warnings.
