typo in debian/rules causing debian package builds to fail

[Patrick Crews]

While attempting to build debian packages for libra to test with, we get this output:

make[1]: Entering directory `/home/jenkins/workspace/lbaas-build-libra-deb/libra'
dh_installinit --name=libra_worker
dh_installinit --name=libra_pool_mgm --no-start
sh_installinit --name=libra_statsd --no-start
make[1]: sh_installinit: Command not found
make[1]: *** [override_dh_installinit] Error 127
