[PATCH] tools/rtla: Restore option to set VERSION var to VERSION file's contents

From 6640548d40a85053cf065f4c66f298bb5253557f Mon Sep 17 00:00:00 2001

In upstream commit 01474dc706ca ("tools/rtla: Use tools/build makefiles
to build rtla") the ``Makefile`` was completely restructered to make
use of the ``tools/build`` infrastructure.

For some reason, the restructuring also caused the ``cat VERSION`` part
to detect the kernel version to be dropped and only runs the
``kernelversion`` (toplevel) Makefile target.
Previously that was used as fallback when ``VERSION`` didn't exist.
Re-add the ``cat VERSION`` part as that is used in the Debian build
system.
