Bump LibZipSharp to 2.0.3

[dellis1972]

We are seeing the following error on some builds

error XABBA7000: Xamarin.Tools.Zip.ZipException: Zip archive inconsistent: entry 0: invalid WinZip AES extra field

Verison 2.0.2 of LibZipSharp was supposed to fix this, but it had a bug.
Which would cause corruption in the zip file itself.

This bug was fixed in 2.0.3 of LibZipSharp. So lets bump to that.

The AndroidManifestProperties("3.1.3a1","42","") test failed, which is slightly concerning:

                   Task "AndroidZipAlign" (TaskId:308)
                     Task Parameter:DestinationDirectory=bin/Debug/ (TaskId:308)

It looks like that file should exist:

                   Task "Copy" (TaskId:301)
                     Task Parameter:DestinationFolder=bin/Debug/ (TaskId:301)

                   Done executing task "Copy". (TaskId:301)

Restarting the tests.

Looks like the restart "fixed" the AndroidManifestProperties("3.1.3a1","42","") test.
