ccmlib/common.py: make java logic more comprehensive

Before this commit `make_cassandra_env` would only find java at
`/usr/lib/jvm/*` directory and could have misconstrue
`java-18-openjdk-amd64` as `java-8`.
This commit makes `make_cassandra_env` to look at any directory under `/usr/lib/jvm` and
to read version from java output
