build-system: asdf: Work around package-name->name+version bug.

Browse Source 
This patch modifies how the name of the main Common Lisp system is extracted
from the full Guix package name to work around bug#48225 concerning the
'package-name->name+version' function.

Fixes <https://issues.guix.gnu.org/41437>.

* guix/build-system/asdf.scm (asdf-build): Fix 'systems' function.
* guix/build/asdf-build-system.scm (main-system-name): Fix it.
