pkgadm code uses external closed makeuuid tool to generate uuids. Now when we have uuidgen in gate, it's better to replace it with uuidgen.

pfexec ./proto/root_i386/usr/bin/pkgadm -vvv lock -a -o aaa && echo 1
[  8109   4] open lock file root </> file </tmp/.ai.pkg.zone.lock-afdb66cf-1dd1-11b2-a049-000d560ddc3e>

We can see that keys have correct format.
