Hmm, that first issue suggests we are not unsetting LD_PRELOAD
before executing programs. Indeed looking at git only the
qemuargv2xmltest and qemuxml2argvtest.c are unsetting LD_PRELOAD.
Seems we should make virTestMain unset LD_PRELOAD globally in
some way.
NB, I'm not objecting to this patch, just saying we shoudl fix
the LD_PRELOAD regardless.

It feels rather recursive to me but if it works...
