Make build reproducible

[davidpolverari]

The current Makefile creates a tarball with files whose permissions vary dependind on the umask.

This patch makes the build more deterministic by adding '--mode=go=rX,u+rw,a-s' to tar command line.

INSTALLDIR should align with new prefix for OpenMRac (/usr/share/openmrac/ -> /usr/local/share/openmrac/) or use the prefix method similar to what you introduced into OpenMRac makefile (I am not exactly sure how it does it, but the expected openmrac.dat path indeed changed).

Hi! I made those changes during the packaging work to include OpenMRac in Debian. I just added the prefix ?= /usr/local line for completeness, to make the Makefile more general and not too Debian-specific. As DIR_OPENMRAC_DAT is defined relative to prefix, I don't think it will present any problems. What problems do you see happening?

BTW, in case you don't know yet, OpenMRac is already in Debian unstable and testing [1] and in Ubuntu [2], as you requested its packaging [3]. Congratulations for the nice game and thanks for making it available!

Oh, sorry for my mistake. I thought you were talking about OpenMRac, not OpenMRac-data. I will have a look at it. I didn't have any problems during packaging, but I will build both in a standalone way with those patches and see if any problem arises.

With the new OpenMRac makefile, I see:
Error loading /usr/local/share/openmrac/openmrac.dat

I believe this should be addressed on the OpenMRac-data makefile side of things.

Thanks for all the effort on your side! I am happy to see the game spreading.

Also, it might be a good idea to also have separate openmrac-gles2 package in Debian (OpenGL ES2 linked build, no game data) - many ARM and Risc-V based SBCs use Debian and have much better ES2 support than desktop GL. Maybe that even is already the case, I don't know because I use Manjaro. Again, just an idea and not required for this PR.

I have merged the OpenMRac PR so that I can remove the deb target because I see it is no longer necessary.

I have tested building and installing with this newest commit, and now it works when building it as presented in README.md.
