net-fs/samba: Apply Flatcar modifications

- Add a minimal USE flag for only installing libraries
  - Change the Perl and Python run-time deps to build-time only
  - Drop a bunch of dependencies with broken cross-compilation
  - Enable using bundled libraries in their place
  - Disable building libraries requiring Python
  - Use EAPI7
  - Move libsxlt and stylesheets to BDEPEND
  - Introduce some USE flags, so we don't install some tools we don't
    need
  - Limit the size of bundled libraries
  - Make it compatible with newer python versions
  - Bump to r2 because of updating EAPI to 7
