Two primary changes of note in this xamarin/LibZipSharp bump:

 1. Bump to `libzip` 1.7.3, which contains numerious fixes and
    improvements over the previously used 1.5.1 release.

 2. Use of `DefaultDllImportSearchPathsAttribute` so that native
    library dependencies are loaded securely, i.e. w/o allowing
    "other" libraries to be loaded from unsafe directories.

Unfortunately, the `libzip` bump itself caused issues, PR #4751 and
PR #4937 each had integration tests "randomly" SIGSEGV.  This was
eventually tracked down to a bug within `libzip` itself, fixed at:

  * nih-at/libzip#202
