crfs/stargz/stargzify: add tool to convert a tar.gz to stargz

And in testing converting the Debian base layer I found a hard link,
so add enough hardlink support (mostly in TODO form) for the tool to
run for now. Proper hardlink support later.

Size stats:

-rw-r--r-- 1 bradfitz bradfitz 51354364 Mar  3 03:32 debian.tar.gz
-rw-r--r-- 1 bradfitz bradfitz 55061714 Mar 21 20:37 debian.stargz

About 7.6% bigger. (Acceptable)
