Mk/Uses/cargo.mk: Add GitLab support and drop CARGO_GH_CARGOTOML

- Add a CARGO_USE_GITHUB equivalent for GitLab instances,
  CARGO_USE_GITLAB
- Replace CARGO_GH_CARGOTOML with a ${FIND} and just patch
  all Cargo.toml under ${WRKDIR}.  It is too tedious to find all
  the Cargo.toml that need patching manually due to transitive
  dependencies.
