Reduce Dockerfile Size

[Lnaden]

Running list of ideas to get the Dockerfile size down.

• Cut down the TeX install
  • Fix issue where all of TeXLive was being installed
  • Determine true minimum set of TeX packages needed
• Reduce CUDA Driver install size
  • De-duplicate the download layer. The 2 commands here download and move/copy the installer file which creates 2 redundant >1GB layers
  • Move the download/and move layers into a single command which ends with removing the downloaded, un-extracted RPM entirely, removing the >1GB layers entirely?

Also welcome to other ideas!

For the later of the CUDA driver, we may need to use a multi-stage build, but that seems to be a pretty new feature. We could alternately add the file from a curl -L command (would need -L instead of -O since its a binary file)

Also consider applying the solution for the CUDA installer to the TeXLive and AMD SDK downloads, since they are also added as part of a Docker ADD directive, then removed when done
