build-system/julia: Enable Julia Pkg to find installed packages.

Julia's built-in package manager (Pkg) looks for packages in
JULIA_DEPOT_PATH/packages/PACKAGENAME/XXXX, where XXXX is a string
encoding package UUID and SHA1 of files.  The link-depot phase creates
a link at the correct location to allow Pkg to find packages that were
already installed by Guix.

* guix/build/julia-build-system.scm (link-depot): New phase.
(%package-path): Modified package path from packages/ to loadpath/.
(project.toml->uuid): New procedure, retrive package uuid from TOML file.
(precompile, check): Adjust to the change in paths.
(%standard-phases): Add link-depot phase.
(julia-build): Add julia-package-uuid keyword.
* guix/build-system/julia.scm (julia-build): Also use the
julia-package-uuid keyword.

[arguments]: Correct paths to reflect change of %package-path modify

directory add package-name-uuid keyword argument to packages without
Project.toml file.
* gnu/packages/julia.scm (julia)[native-search-paths]: Correct paths to
reflect change of %package-path modify order of phases as link-depot
needs to run on an unmodified src directory.
