[RFC PATCH 4/8] tests/pytest: add pytest to the meson build system

[Thomas Huth <thuth@redhat.com>]

From: Ani Sinha <ani@anisinha.ca>

Integrate the pytest framework with the meson build system. This
will make meson run all the pytests under the pytest directory.

[thuth: Removed the acpi-bits and adjusted for converted avocado tests instead]
