libs/xmlrpc-c: fix xmlrpc-c-abyss and xmlrpc-c-server-abyss packages

When building abyss feature, the following error occurs:

xmlrpc_server_abyss.c:783:13: warning: format not a string literal and
no format arguments [-Wformat-security]
783 | xmlrpc_faultf(envP, error);

Add a patch fixing the format parameter.
