dante: Do not export rresvport where it does not exist

Extend the version script patch to also leave out rresvport() when
configure does not find it, as on musl, where lld fails with:

  error: version script assignment of 'global' to symbol 'rresvport' failed: symbol not defined

-dlib only interposes getipnodebyname() and freehostent() when the

-the exported symbols, so with glibc linkers that check the version
-script, like lld, fail with:

-
-Leave them out of the symbol list when getipnodebyname() is not found.
