gnu: aalib: Really build the shared library on powerpc64le-linux.

Fixes <https://issues.guix.gnu.org/57134>.

The old build scripts were buggy and causing a static library to be produced
instead, which would fail to be linked by gst-plugins-good.

* gnu/packages/video.scm (aalib) [native-inputs]: Remove labels.
[arguments]: Use gexps.
<configure-flags>: New argument.
<phases>: Remove update-config-scripts and configure override.
Add force-autoreconf.
