rpc.idmap: Hide global symbols from libidmap plugins

This patch limits the visibility of the symbols in the nfs-utils
conffile.c so that they are only visible to programs linked directly to
it.  This forces the objects dynamically loaded via libnfsidmap to use
the functions defined in that shared library instead.
