openjdk-8-common: Fix warning evaluating CFLAGS

Code is (on my opinion) simpler, making use of the dumpversion flag, instead of calling the pre-processor via a pipe.

Flag has been tested on both clang gcc:

ricardo@neopili:~/curro/qt5022/build-qt5022-pyro/repo/java$ gcc-4.8 -dumpversion
4.8
ricardo@neopili:~/curro/qt5022/build-qt5022-pyro/repo/java$ gcc-4.9 -dumpversion
4.9.3
ricardo@neopili:~/curro/qt5022/build-qt5022-pyro/repo/java$ gcc-5 -dumpversion
5.4.1
ricardo@neopili:~/curro/qt5022/build-qt5022-pyro/repo/java$ gcc-6 -dumpversion
6.4.0
ricardo@neopili:~/curro/qt5022/build-qt5022-pyro/repo/java$ gcc-7 -dumpversion
7
ricardo@neopili:~/curro/qt5022/build-qt5022-pyro/repo/java$ clang-4.0 -dumpversion
4.2.1

Without this patch:
