So I added O_TRUNC to both of the callers to /selinux/context in
libselinux and that took care of the lsetfilecon() crap but I still
get tons and tons of "scriptlet failed, exit status 255"
Anyone have ideas/suggestions how to debug those more?

These all look like library packages so I'd hazard a guess that the
thing that's failing is ldconfig. Perhaps you could replace ldconfig
with a wrapper than runs it under strace?
