remove RPC implementation

The included RPC implementation is ipv4 only.
Other C library projects have either deprecated the internal
RPC implementation (GNU C Library) or never implemented such
functionality (musl C Library). The latest rpcbind release (0.2.4)
checks for libtirpc and does not allow to be build with uClibc-ng
RPC without patching. The common use case for RPC nowadays is to
use rpcbind together with nfs-utils to provide NFS server or client
support to a system.

The included RPC implementation does create issues with duplicate
symbol failures when statically compiling with RPC enabled.

- * This interface must manage two items concerning remote procedure calling:
- *
- * 1) An arbitrary number of transport connections upon which rpc requests
- * are received.  The two most notable transports are TCP and UDP;  they are
- * created and registered by routines in svc_tcp.c and svc_udp.c, respectively;
- * they in turn call xprt_register and xprt_unregister.
- *
- * 2) An arbitrary number of locally registered services.  Services are
- * described by the following four data: program number, version number,
- * "service dispatch" function, a transport handle, and a boolean that
- * indicates whether or not the exported program should be registered with a
- * local binder service;  if true the program's number and version and the
- * port number from the transport handle are registered with the binder.
- * These data are registered with the rpc svc system via svc_register.
- *
- * A service's dispatch function is called whenever an rpc request comes in
- * on a transport.  The request's program and version numbers must match
- * those of the registered service.  The dispatch function is passed two
- * parameters, struct svc_req * and SVCXPRT *, defined below.
