net-p2p/freenet: Fix build and runtime errors with JNA 5.x

This package uses JNA's Pointer.SIZE API, which has been removed since
JNA 5.0.0.  A replacement of the API is Native.POINTER_SIZE, which is
present in both JNA 4.x and 5.x.

Since JNA 5.0.0, the default JNI library loading mechanism has been
changed, which would cause this package to crash upon launch, unless
system property 'jna.nosys' is set to 'false', which restores the 4.x
library loading behavior compatible with this package.

+Subject: [PATCH] Replace Pointer.SIZE with Native.POINTER_SIZE for JNA 5.x
+
+This patch is backward compatible with JNA 4.x because
+Native.POINTER_SIZE is present in both 4.x and 5.x.
