Remove zfs ebuilds

From https://bugs.gentoo.org/show_bug.cgi?id=906429:
```
sys-fs/zfs-0.8.6: failed sourcing ebuild: No supported implementation in PYTHON_COMPAT., (python-utils-r1.eclass, line 171: called die)
sys-fs/zfs-0.8.9999: failed sourcing ebuild: No supported implementation in PYTHON_COMPAT., (python-utils-r1.eclass, line 171: called die)
```

Instead of patching the old ebuilds (and perhaps zfs-0.8.6 itself)
to support the newer Python versions,
just remove the zfs-with-beadm-included forked ebuilds
and use the standalone beadm ebuild.

Other included changes:
- bemerge: Depend on zfs, since it uses libnvpair from it.
- Merge `beadm.keywords` into the main `linux-be.keywords`.
- Remove `linux-be-zfs-*.keywords`.
- README.md: Update wiki link (the current one is broken).
- `sanity.sh`: Remove checks for `zfs*` ebuilds.

Upgrade instructions:
- Remove broken symlinks to keywords:
```
rm -f /etc/portage/package.accept_keywords/linux-be-zfs-master.keywords
rm -f /etc/portage/package.accept_keywords/linux-be-zfs-0.7.keywords
rm -f /etc/portage/package.accept_keywords/linux-be-zfs-0.8.keywords
rm -f /etc/portage/package.accept_keywords/linux-be-zfs-0.8.9999.keywords
rm -f /etc/portage/package.accept_keywords/beadm.keywords
```
- If still using `zfs{,-kmod}:0/libbe` ebuilds,
see !20 for switching to `beadm` ebuild
and Gentoo-provided `zfs{,-kmod}` ebuilds.

sys-apps/beadm: Conflict with zfs:0/libbe

The ebuilds install the same files.
sys-apps/beadm should be used with regular zfs ebuilds.
