The macro HAVE_GETRPCBYNUMBER_R is set based on whether the
`getrpcbynumber_r` function was found by autoconf or not. While another
location correctly checks whether it is set by using `#ifdef`,
`getservport()` instead wrongly uses `#if HAVE_GETRPCBYNUMBER_R`. This
may cause a compilation error with gcc with "-Werror=undef" if the macro
has not been defined.

Fix the error by using `#ifdef` instead.
