Update to more recent Tycho

To be able to use location type Maven in target file we need a more
recent Tycho version.

Instead of updating to latest (5.x) version of Tycho, we limit to 3.x
version so that we can maintain compatibility with older Eclipse
target platform. Embed CDT uses 2020-09 as target platform.

The build requires a newer Java version, but the built artifacts continue
to run in Java11+ on Eclipse 2020-09+.

Fixes #646
