s4:heimdal_build: move krb5-types.h into include/krb5-types.h

s4:heimdal_build: move krb5-types.h into include/krb5-types.h

source4/heimdal_build/include/ contains public headers,
which are needed by callers.

source4/heimdal_build/*.h should only be used for building the
in tree heimdal itself.

Without this an '#include "replace.h"' can catch 'config.h' from
source4/heimal_build/config.h before bin/default/include/config.h.
This #defines HAVE_CLOSEFROM unconditionally before replace.h can define
the replacement for rep_closefrom() on systems without libbsd.
