[oe] [meta-java][PATCH 2/3] ca-certificates-java: Don't fail when called via hook on do_rootfs

[Yevgeny Popovych]

It is possible that ca-certificates-java hook will be called via
update-ca-certificates hook during do_roofs (the case when D is set
and JVM_LIBDIR is not).
This is a valid case so don't fail.
