suzerain: #2856 use non-patched, older libtool

I want a saner place from which to debug this RPATH issue.
One good starting point is a vanilla set of libtool stuff.
Has the benefit of moving to the classical autoreconf bootstrap.

suzerain: use subdir-objects

Mildly cleans up suzerain/ by pushing things into suzerain/support.
Might be a path forward for the various convenience libraries...
