python/aqmp: use absolute import statement

python/aqmp: use absolute import statement

pylint's dependency astroid appears to have bugs in 2.9.1 and 2.9.2 (Dec
31 and Jan 3) that appear to erroneously expect the qemu namespace to
have an __init__.py file. astroid 2.9.3 (Jan 9) avoids that problem, but
appears to not understand a relative import within a namespace package.

Update the relative import - it was worth changing anyway, because these
packages will eventually be packaged and distributed separately.
