lang/rust: Cleanup part 4

- Spell LICENSE_FILE_APACHE20 correctly
- Move gmake to BUILD_DEPENDS directly.  gmake is called during the
  build by some crates but is not the primary build tool.
- Move variables around to be more in line with the recommendations
  in the Porter's Handbook
- Mark port local non-overridable variables as "private"
- Reduce noise of RUST_ARCH_*: only keep the overrides when they
  differ from ${ARCH}
- Drop unused RUST_TARGET plist sub
- Move post-configure-DOCS-* into do-configure
