[PATCH] tests/functional/x86_64/test_acpi_bits: Silence warnings reported by pylint

[Thomas Huth <thuth@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

Pylint complains about too many positional arguments for the __init__
function of the QEMUBitsMachine class, use a "*" to enforce argument
passing by names instead (which the calling sites are doing here already).

Second, use lazy logging when calling self.log.info() with a "%s" format
string, and drop a superfluous "else:" that is not necessary after a
"raise" statement.
