Repocopy from linux_base-gentoo-stage2 to emulators/linux_dist-gentoo-stage2.

These ports are complete Linux distributions rather than linux_base ports and
don't really suit our Ports Collection infrastructure,  so
they should be renamed to emulators/linux_dist-gentoo-stage[123], but the
opportunity to install them as linux_base should be kept.
After the repocopy the patches mentioned below should be applied

- Add WITH_LINUXBASE for using as a linux_base, otherwise it installs
  under ${PREFIX}/${PORTNAME}
- Add an explanation in pre-fetch to explain WITH_LINUXBASE
- Move pkg- scripts into files/ to reinplace-edit them appropriately
- Change to static plists
- do-extract is unnecessary now since we have static plists
- Drop alpha support for linux_base-gentoo-stage1 since
  1, alpha support was dropped in CURRENT as well, and RELENG_[56]
     are badly maintained for alpha
  2, I don't have hardware to test these changes for alpha
- Bump PORTREVISION
