Bump to a more modern version of bnd

Hoping to avoid an NPE I saw in the scala/scala build
while working towards Java 10 support.

My NPE looked the same as the one described in
gradle/gradle#2583, an issue
which was resolved by update bnd.

The artifact name seems to have changed in 2015
between 2.4.0 and 2.4.1
