[libvirt] [PATCH] test: fix commantest under autobuild.sh

[Eric Blake]

* tests/commandtest.c (mymain): Kill off any leaked-in fds.
* autobuild.sh: Don't leak fds.

Autobuild failed because it triggered a commandtest failure where
commandtest was too sensitive to the environment.  Fix the problem
at both ends - autobuild shouldn't leak, and commandtest should
work even when somebody else leaked.
