- Delete obsolete patches and fix the rest.
- Add pkg-config (otherwise, undefined talloc_* refs abound).
- Use docs/GNUMakefile to generate manpage.
- Force Makefile to recognize package version.

Subject: Disable seccomp-based tracing performance improvement
It is faster (according to upstream documentation), but on current
(4.8.4+) kernels it just segfaults. Software that works slowly seems
better than software that doesn't work at all.
