build: fix virtlockd file distribution

Since virtlockd is only built when libvirtd is built, we should
not install its auxiliary files unconditionally.  This solves
two failures.  1. 'make distcheck' complains:

rm -f Makefile
ERROR: files left in build directory after distclean:
./src/virtlockd.8

2. './autobuild.sh' complains:

Checking for unpackaged file(s): /usr/lib/rpm/check-files
/home/eblake/rpmbuild/BUILDROOT/mingw-libvirt-1.1.1-1.fc19.eblake1377879911.x86_64
