build: In-build and post-installation test steps.

[Artoria2e5]

Two kinds of tests need to be implemented:

autobuild/test

Occurs before installation.

autobuild/abtest

Part of abscripts abstraction, for non-supporting PMs install to /var/ab/tests/$PKGNAME.

# /usr/bin/ab-testpackage
if package manager has support; then exec out; fi
abbl-invoke "/var/ab/tests/$PKGNAME"

Occurs before installation.

Might as well just change that to a switch to whether to run unit tests or not.

As an side, some good test can also be fed to AutoFDO…
