Fix Debian package dependencies

* debian/control (Build-Depends): Changed GnuTLS dependencies to
                                  "libgnutls30 (>= 3.3.0),
                                  libgnutls28-dev (>= 3.6.6) |
                                  libgnutls28-dev (<< 3.6.0)".  (We
                                  can't depend on the virtual package
                                  "gnutls-dev", since we need the
                                  version restrictions.)
  (Package: mandos/Depends): Remove dependency on libgnutls28-dev
                             package.
  (Package: mandos/Suggests): New; set to "libc6-dev,
                              c-compiler". (Used to find value of
                              "SO_BINDTODEVICE").
  (Package: mandos-client/Depends): Don't depend on openssl anymore;
                                    instead depend on either a
                                    gnutls-bin (>= 3.6.6) (in which
                                    case TLS key generation will
                                    work), or on libgnutls30 (<<
                                    3.6.0) (in which case TLS key
                                    generation will not be needed).
