Subject: extreload.asd: Compress SBCL executable

The default executable compiled by SBCL is huge. Copied code from:
https://lispcookbook.github.io/cl-cookbook/scripting.html#building-a-smaller-binary-with-sbcls-core-compression
to produce a smaller executable.

Here's the size comparison:

$ du -hs extreload*
 11M	extreload-ecl
 58M	extreload-sbcl
 15M	extreload-sbcl-compressed
