build-sys: introduce $sysconfstaticdir

The current situation is that distros differentiate between:

* host specific configuration -- usually /etc, maintained by admin

* distribution specific (static) configuration -- usually /usr/lib,
  maintained by ditro packages

Unfortunately autotools have clue about $sysconfdir (/etc) only. This
patch introduces $sysconfstaticdir (default $prefix/lib).
