Impala allows various Java versions to be selected for its build and
runtime environment when bin/bootstrap_system.sh is used to set up the
environment. Unfortunately this setup failed to affect the current Java
JRE and compiler tools on Red Hat Linux and compatibles (e.g. Rocky
Linux), because bootstrap_system.sh failed to set up the requested
version in the "alternatives" subsystem. The same failure was not
observed on Ubuntu versions, on that platform `update_java_alternatives`
was correctly run for the same purpose.
This patch adds calls to `alternatives` to set the JRE and JDK
environments to the requested version. This benefits automated test runs
in Impala's pre- and post-commit environments as well as individual
workstation setups.
