autofs-5.0.6 - fix libtirpc name clash

From: Ian Kent <ikent@redhat.com>

The tirpc function auth_destroy() is a macro definition in tirpc/rpc/auth.h
which includes an unconditional call to a function log_debug() which clashes
with an autofs function of the same name and has a different call signature.

To fix it redefine auth_destroy() and exclude the debug log call.
