packaging: detect java home at runtime

CURRENT IMPLEMENTATION

detect java home during installation.

advantage is optimize application execution post-setup.

disadvantage is that java home may be altered by system updates.

NEW IMPLEMENTATION

detect java home during runtime using pre-defined algorithm.

algorithm:

execute /usr/share/ovirt-engine/bin/java-home.

if java-home.local is available, execute that script. this enables
distro specific customization.

if OVIRT_ENGINE_JAVA_HOME environment is set, validate java validity
and use/abort.

search predefined selected alternatives location by order, first wins.

search /usr/lib/jvm for compatible jvm.

NOTES

the java-home script resides with the lib package as it cannot reside
within any version locked package since it is used by setup, and it
cannot reside within setup since it used by post setup.
