xemacs-packages.eclass: Support EAPI 6.

- Do not export src_compile, as using the default has the same result.
- Precede PKG_CAT and EXPERIMENTAL variables with XEMACS_ for proper
  namespace.
- Explicitly assign S, because there is no fallback to WORKDIR in
  recent EAPIs.
- Move install directory logic into src_install function.
- Install into ${D}${EPREFIX} rather than ${D}.
