Version numbering changes

[Max Khon]

Hello,

I see a number of commits that fix things after recent numbering changes
were committed.

However there are more issues to fix:

1) Dockerfile.deps do shallow clone of freeradius git repo. So "git
describe" then fails with

fatal: No names found, cannot describe anything

As a result docker builds have no RADIUSD_VERSION_INCRM defined.

2) .spec files expect freeradius-server-4.0.0.tar.bz2 to exist but "dist"
target now creates freeradius-server-$(PKG_VERSION).tar.bz2 and
$(PKG_VERSION) includes $(RADIUSD_VERSION_INCRM)
