[bug#73075] [PATCH 2/2] gnu: gap: Build most packages.

[Andreas Enge]

* gnu/packages/algebra.scm (gap)[source]<snippet>: Use a blacklist instead
of a whitelist.
[inputs]: Add inputs required for packages.
[license]: Use gpl3+ for the combined work.
[arguments]<#:phases>: Set CC environment variable.

This change is possible since now all licenses for GAP packages are
properly documented as free. Packages are only excluded if they currently
fail to build, as a reminder for further work.
