Subject: [PATCH] gptfdisk: rebuild

* gptfdisk: fix compile on Big Sur
  * Starting on 11.0, OS/X doesn't have physical files appearing
  as /usr/lib/*.dylib for the standard libraries, but the toolchain
  can still link against them (using the .tbd files inside the SDK
  to guide it)  Just use "-lncurses" which seems to work.

  * "brew test" wouldn't work for me.  The first problem was that
  hdiutil doesn't seem capable of creating a 128k disk image any more,
  but the command works when I run it manually with a 512k size.
  However, it still doesn't work due to a permission issue when
  running inside "brew test" -- I think something changed in how
  the test sandboxing works so that hdiutil can no longer run.
  (hdiutil can need expanded permissions since it temporarily
  mounts the new image I think)  I couldn't find a clean way
  to work around it so I just changed the test to use this package
  itself to make the test partition.  A better test in some ways,
  a worse test in others.

  * Tweak the license info to make "brew audit" happy
* gptfdisk: tweak test code style per review

Closes #66304.
