build: reduce Extra contents to bare minimum

Improve the build system, so that configuration files are installed
per tool basis. Also, introduce post_install targets, so that config
files can be altered in some way, e.g. done by trafgen. Moreover,
move custom targets from Extra to tool-specific Makefiles.
