[FTBFS] ceph fails to build with openjdk-9

[Tiago Stürmer Daitx]

ceph 12.2.2-0ubuntu2 FTBFS when building with openjdk-9 due to source/target being set to 1.5. OpenJDK 9 requires at least 1.6, but since OpenJDK 10 is due by this month and OpenJDK 11 LTS by september this year, it is safer to update both target and source to 1.8 so even OpenJDK 11 can be used to build it.

Building with openjdk-9 on bionic was tested locally and in a ppa, both reported success.
