lang/sbcl: Hook into the FreeBSD ports asdf framework by depending on devel/cl-asdf and loading etc/asdf-init.lisp in sbclrc.

[jrm]

Summary

Also:

• bump PORTREVISION
• download SBCL bootstrap binaries from official upstream source instead of the FreeBSD cluster

Optional nick-picky changes:

• use DISTVERION instead of PORTVERSION
• fix portlint warnings about ordering
• use variables; e.g., ${PORTVERSION} instead of repeating sbcl

Test Plan

portlint -C: three spurious warnings
poudrirere testport: 10/11 i386/amd64: ok
