makefile: FLAVOUR support

Basic support for sip-router, ser and kamailio flavours and
install flavours, e.g.:
make config FLAVOUR=sip-router
make config INSTALL_FLAVOUR=kamailio; make install (will install
only kamailio specific tools, but won't change the main name)
make config FLAVOUR=ser; make install (will install ser tools and
change the name to ser).

Note that FLAVOUR does not influence the module list (one should
use modules_dirs, group_include and/or modules, modules_s,
modules_k) and that for now choosing kamailio will only change the
name.
