[gentoo-dev] [PATCH] python-utils-r1.eclass: epytest, error out on missing async plugin

["Michał Górny" <mgorny@gentoo.org>]

Explicitly error out if epytest is run without an appropriate async
plugin, and the test suite contains async tests.  Currently, these tests
are skipped with a warning but that is usually a mistake, and one can
easily miss it when pytest-asyncio or a similar plugin is installed
on the test system.  However, a missing dependency can result
in the tests being skipped afterwards on the tinderbox.
