=app-arch/xz-utils-5.4.0 supports lzip decompression (not compression).

Add support for unpacker.eclass to handle it for .lz files.

Note that xz-utils is part of @system (and PMS requires that .xz is unpackable),
while most users do not have lzip and friends installed.

(Note that xz does not (currently, but does not plan on either) implement parallel decompression for .lz, but most .lz distfiles are small, so this
isn't an issue.)

Historically, we've often repacked .lz distfiles for important packages
to avoid users needing to install app-arch/lzip for a single distfile,
so this avoids the need for that (although I've not done it out of
principle for things like sys-apps/ed).

Shouldn't all consumers with a dependency on lzip be revbumped?
Otherwise emerge --depclean (in the default configuration) won't drop
lzip.

That seems like an extreme solution to a problem nobody really cares about.

We can do that once xz-utils-5.4.x is stable to avoid doing it twice,
I suppose.
