MINOR: Update dependencies for Kafka 2.4 (#7126)

Scala 2.12.9 brings another 5% ~ 10% improvement in compiler performance,
improved compatibility with JDK 11/12/13, and experimental infrastructure for
build pipelining.

zstd update includes performance improvements, among which the
primary improvement is that decompression is ~7% faster.

-- | -- | -- | --
1 | 1390 MB/s | 1453 MB/s | +4.5%
3 | 1208 MB/s | 1301 MB/s | +7.6%
5 | 1129 MB/s | 1233 MB/s | +9.2%
7 | 1224 MB/s | 1347 MB/s | +10.0%
16 | 1278 MB/s | 1430 MB/s | +11.8%

Jetty 9.4.19 includes a number of bug fixes:
https://github.com/eclipse/jetty.project/releases/tag/jetty-9.4.19.v20190610
