Use @LIBO_URE_SHARE_JAVA_FOLDER@ instead of hardcoding ../share/java

Makes CppunitTest_dbaccess_hsqldb_test work also in the
--enable-canonical-installation-tree-structure (on OS X), otherwise
the use of $URE_INTERNAL_JAVA_CLASSPATH (looked up from the URE unorc)
in stoc/source/javavm/javavm.cxx fails.

Use @LIBO_URE_LIB_FOLDER@ for URE_INTERNAL_LIB_DIR

In the --enable-canonical-installation-tree-structure case (on OS X),
the URE unorc is definitely not in the same place as any libs. Noticed
in JunitTest_comphelper_complex.

Use LIBO_URE_BIN_FOLDER and LIBO_SHARE_JAVA_FOLDER

Needed in case of --enable-canonical-installation-tree-structure.

Ugly hack to fix build when srcdir!=builddir

The problem is that the ure/source/unorc file is now expanded by the configure
script, and thus exists only in builddir. But a further complication is that
the uno.ini file is in srcdir. This is one way to handle it. Seems to work for
me, let's see what the srcdir!=builddir tinderbox slaves say.

"fixes" needed because ure/source/unorc is now expanded at configure time

Argh, this is getting even uglier.

We cheerfully ignore for now the theoretical possibility that the URE
unorc used by build-time tools (i.e. the configure-expanded
ure/source/unorc) could be different for HOST and BUILD (in case they
use different --enable-canonical-installation-tree-structure), and use
the HOST one for the BUILD tools.

The right thing would probably be to construct the URE unorc in the
relevant Makefile, like we do for fundamentalrc? Or then to just
re-design the whole mess of rc files into some simpler (good luck).
