bundleTask improperly transmits resource directories to bnd

The `Osgi.bundleTask` function passes resource directories to **bnd** via the `INCLUDE_RESOURCE` constant, which causes the (absolute) pathnames to be copied into the `Include-Resource` in the generated `MANIFEST.MF`, exposing information about the user's build environment to the world.

`Osgi.bundleTask` should instead be passing the resource directories to **bnd** via the `INCLUDERESOURCE` constant, which corresponds to the `-includeresource` option and does not cause the information to be copied into the `MANIFEST.MF`.

The attached commit contains this one-character fix.
