Set URE_INTERNAL_JAVA_DIR for unorc to allow jvm in unit tests.

Currently unit tests run in solver, the unorc in solver is simply
copied from cppuhelper/source/unorc, which doesn't set
URE_INTERNAL_JAVA_DIR, hence the jvm cannot be loaded in Unit tests.

(For comparison the URE unorc in instdir is copied from ure/source/uno{rc,.ini}
and contains the appropriate java paths.)

(URE_INTERNAL_JAVA_CLASSPATH is not needed, at least currently.)
