Reduce bundled javacv library size

With the introduction of the javacv library when re-adding the QR code
scanner feature for mobile notification pairing in #7050, the Bisq
binary increased to nearly 1 GB from its previous size of around 300 MB.

When including the javacv-platform dependency, it pulls in binaries
for all platforms. But it is possible to limit this by utilizing
the gradle-javacpp platform plugin which by default will pull in
binaries only for the current platform.

With this change, the included libs went from ~980 MB down to ~366 MB.
