Create matlab-runtime

Allow multiple versions of the Matlab Runtime. For that we need to
include the version in the package name and make sure each version
is installed alongside other versions.

Note that the package version is simply the update number, 9 in the
case of the 9.7/R2019b Linux binary:
	MATLAB_Runtime_R2019b_Update_9_glnxa64.zip

For now, keep the package non-relocatable. The `patchelf` tool fails
with obscure error messages on MATLAB Runtime binaries.
