Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

- Add a "real" symbol version map to libasn1. The upstream version
of the version map just exported all the symbols, which caused a
binutils bug being triggered when ld fails to link two objects, one
of which exports a versioned version of the symbol, and another --
unversioned. [1]
- Also add version map for libkafs5.
