mkdeb.sh.in: stop running ./configure

On firejail 0.9.68, one would run `./configure` (to generate Makefile
from Makefile.in) and then running `make deb` would end up running
something akin to:

    make distclean && make dist && ./configure --prefix=/usr && mkdeb.sh

As of netblue30#5142, `make dist` does not run `make distclean` anymore, but
`make deb` still overrides any configure options that the user might
have set.

Stop doing that and do just `make dist && mkdeb.sh` on `make deb`.

To build everything from scratch as `make deb` would do on 0.9.68 (but
without it overriding the configure options), one can run:

    make distclean && ./configure --prefix=/usr && make deb

Note that this is basically what the "build_debian_package" job on
.gitlab-ci.yml does (see also the "build_apparmor" job).

Should fully fix netblue30#3523.

Relates to netblue30#772 netblue30#1205.
