New package: openjdk-common-1

Replaces the xbps trigger that added the profile script for openjdk,
which was really a mistake.

Instead of using alternative groups for specific JRE/JDK binaries, use
two symlinks: /usr/lib/jvm/default-jdk and /usr/lib/jvm/default-jre,
which point to /usr/lib/jvm/${version}. Prefer default-jdk to default-jre,
and just add them to PATH and MANPATH instead of putting things in /usr/bin.
