sunrpc: Remove stray exports without --enable-obsolete-rpc [BZ #23166]

Browse Source 
This is needed to avoid a warning when linking against libtirpc:

/lib64/libc.so.6: warning: common of `rpc_createerr@@TIRPC_0.3.0' overridden by definition
/usr/lib64/libtirpc.so: warning: defined here

This ld warning is not enabled by default; -Wl,--warn-common enables it.

[BZ #23166]
* include/rpc/clnt.h (rpc_createerr): Declare hidden alias.
* include/rpc/svc.h (svc_pollfd, svc_max_pollfd, svc_fdset):
Likewise.
* sunrpc/rpc_common.c (svc_fdset, rpc_createerr, svc_pollfd)
(svc_max_pollfd): Add nocommon attribute and hidden alias. Do not
export without --enable-obsolete-rpc.
* sunrpc/svcauth_des.c (svcauthdes_stats): Turn into compatibility
symbol. This should not have been exported, ever.
