rS350436: Remove gzip'ed a.out support.

Summary

Remove gzip'ed a.out support.

The current implementation of gzipped a.out support was based
on a very old version of InfoZIP which ships with an ancient
modified version of zlib, and was removed from the GENERIC
kernel in 1999 when we moved to an ELF world.

The changes look okay.

Should we ask kib to review as well?
I recall he had strong motivation keeping a.out executable format support although he didn't seem to much care about gzip'ed a.out.

Fine with me

It's my belief this hasn't worked in a long time. Maybe not since at least FreeBSD 4 or 5 (or maybe even 3 when it was retired). I've seen reports since 6 that it's broken.

Someone mentioned https://svnweb.freebsd.org/base?view=revision&revision=231885 was trigger in one of the mailing list. Anyway, if that's true, it's been broken for 7 years.
