declare replacement [v]asprintf functions

If HAVE_VASPRINTF is not defined, make sure krb5int_{,v}asprintf
functions always get declared, applying the preprocessor conditional
test only to the GCC format attribute.  If HAVE_VASPRINTF is defined,
don't declare them at all.

This fixes a bunch of function-not-declared warnings under Sun cc.
