README: Cleanup description of supported partitions.

Signed-off-by: Karl O. Pinc <k...@meme.com>

I'm still trying to figure things out, and so am trying to
clarify the docs as I go.  FYI, I'm fuzzy about:

Whether this should read "One or more" or "Zero or more".

Whether the 2TB limit noted in disk/part_efi.c is really
still true.

Whether this list is comprehensive.

Whether this list is overly chatty/pedantic.

Whether these sorts of changes should be in the wiki,
the README, or both.
