Bnd vs osgi

[gurpreet-]

@mhilbush Lazysodium would like to upgrade to Gradle 6. The plugin osgi was removed in Gradle 6.

Instead I have switched to using Bnd: https://github.com/bndtools/bnd/blob/master/biz.aQute.bnd.gradle/README.md#replacing-use-of-gradles-deprecated-osgi-plugin

Is this okay? I can submit a lazysodium 5.0.1 with these changes in to see if it causes any grief?

Yes, that would be great. Thanks!!
