[Opendnssec-develop] kaspcheck replacement

[Siôn Lloyd]

I've done some testing on the new kaspcheck script and I think that it 
behaves in (roughly) the same way as the ruby version. (One change is 
that it now exits early if the xml doesn't pass the rng tests.)

So, I've changed the makefile in the enforcer/utils directory to build 
and install it.

N.B. if you also build the auditor then the c version will be overwritten!

There are some tests (enforcer/test/kaspcheck), written in ruby, that 
are based on the old tests. Hopefully these can be called from jenkins; 
this means that we will have a ruby requirement in our test environment.

Enjoy.
