package/vtun: update to 3.0.3

Against all odds, vtun had a new release sometime last year.

Still, the code needs patching:
  - the existing patch to fix installation has been refreshed
  - the existing patch to fix blowfish header location has been
    replaced (see below)
  - configure looks in hard-coded, host paths (eg. /usr/include)
    without any consideration for scross-compilation
    --> new patch
  - configure.in does not even pass an autoreconf without a
    bit of love first (it's written in an ancient dialect that
    autoreconf does no longer recognise)
    --> new patch

Remove obsolete, unused, bit-rotting scripts and warning.

-Previous vtun was version 2.6.
-This does not buld because its "configure" requires
-that -llzo contains "lzolx_decompress".
-"vtun" does not build, evenm if liblzo is available.
-
-The LZO package currently used by buildroot
-does not contain ANY reference to "lzolx_decompress"
-
-"vtun" has been upgraded to 3.0.2 and now builds OK,
-but is yet to be tested on a target.
-The previous patch containing three diffs,
-has been broken up into three files.
-
-The second patch fails.
-
-This patch tries to replace a perl script
-($(VTUN_DIR)/scripts/vtund.rc.debian)
-with a shell script with the same name.
-
-In vtun-3.0.2, vtund.rc.debian is a shell script which is
-fairly similar to the shell script provided by the patch.
-For now, it has been decided not to replace this shell 
-script with the script generated by the patch for 2.6
-
-vtun will thus be built with the 3.0.2 vtund.rc.debian.
-The start-stop-daemon parameters and other things
-in this script may be inappropriate for something based on busybox.
-
-I will leave the decision which script to use,
-the 2-6 script or the 3.0.2 script to someone else.
-
-Both files are kept in the directory, but should
-be removed once it has been decided what to do
-about this script.
