[RFE] enable lib.private via RPATH

[heitbaum]

Use RPATH to target local lib.private shared libraries. This keeps the shared libraries from polluting the LD_LIBRARY_PATH. Add the following RPATH to the binaries '$ORIGIN/../lib.private'

tested using patchelf

$ patchelf --add-rpath '$ORIGIN/../lib.private' rar2fs
$ patchelf --print-rpath rar2fs 
$ORIGIN/../lib.private

shown below

nuc12:~ # ldd .kodi/addons/virtual.network-tools/bin/rar2fs.rpath
        linux-vdso.so.1 (0x00007ffd39bd8000)
        libfuse.so.2 => /storage/.kodi/addons/virtual.network-tools/bin/../lib.private/libfuse.so.2 (0x00007f322f01f000)

        libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0x00007f322ede3000)

• for sundtek - how are these .so files used?
• for jre - how/when are the X11 libraries included. Need to test - but maybe simple addition of $ORIGIN/../../lib.private

$ cd build.LibreELEC-Generic.x86_64-12.0-devel/addons/jre.zulu:target/tools.jre.zulu/jre/bin
$ patchelf  --print-rpath *

Updating labels to LE13. The 2 remaining packages to be fixed are sundtek and jre.
