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.
