deps-lock missing deps for tools alias target

[sg-qwt]

When alias is added as tools alias in deps.edn:

https://clojure.org/guides/tools_build#_setup

example:

{:paths ["src"] 
 :deps {} 

 :aliases
 {
  :build {:extra-paths ["build"]
              :extra-deps {io.github.clojure/tools.build {:mvn/version "0.9.6"}}
              :ns-default build}}}

        {:keys [src-dirs basis output-jar]} (common-compile-options opts)]

When you run clojure -T:build uberjar :lib-name 'xx/xx' :version 'dev' :main-ns 'xx.core' first time for example, you'd observe tools alias is downloading

Those deps do not get added when processing deps.edn with alias :build, thus when using buildCommand

            buildCommand = ''
              clj -T:build uberjar :lib-name '${name}' :version '${version}' :main-ns '${main-ns}'
            '';

would cause the build to fail due to those missing ones from deps-lock.json
