shlibafsauthent: Add a load more objects

The perl-AFS module needs to link against a pthreaded, PIC, library
that contains all of the routines that it provides perl shims for.
At the moment, libafsrpc_pic and libafsauthent_pic are the only such
libraries that OpenAFS provides.

Add all of the necessary objects to libafsauthent_pic such that the
2.6.2 version of perl-AFS can build with a minimal set of patches.
Minimise the damage by only making these available through the static
version of the libafsauthent_pic library.

This is a 1.6 version of this change, which adds some additional
symbols and objects to cater for differences between master and 1.6
The changes aren't relevant to master, as the whole shared library
situation there is now completely different.
