OpenBSD doesn't have /etc/environment, therefore there is no

need to fiddle with it. The default case statement, "do nothing"
is all fine here.

Facter::Util::Resolution.with_env is long time gone since
Facter > 2.x. That was even longer before introduced by me.
Remove that OpenBSD special case in the java_version fact,
and assume that $PATH is properly set in order to find
the 'java' binary.

Additionally confine the java_default_home and java_libjvm_path
to OpenBSD kernel as well. Add some flesh to the java_default_home
fact to allow it to find the java binary.
