Subject: [PATCH] Make java version check work on all shells (#9376)

* Make java version check work on all shells

Previously, "perl verify-java" would fail on shells like zsh, which
would cause the quickstart scripts (e.g., bin/start-micro-quickstart) to
fail unless the DRUID_SKIP_JAVA_SKIP environment variable is set.

* Support dash (ubuntu)
