Revert problem.relativistic-limo.tex back to expecting `limo.*`.

This reverses a portion of

    Make the Python limo script executable.

    Also adjust the name of the expected file to ${SCRIPT/.py/} to
    make it easier to automatically generate the required image.

The new scheme works with

  TARGET="$(echo "${SCRIPT}" | awk -F. '{print $(NF-1)}').png"
  "${SCRIPT}" "${TARGET}"

This avoids problems like

  LaTeX Warning: File `problem.relativistic-limo.limo' not found on
  input line 50 .
  ! LaTeX Error: Unknown graphics extension: .relativistic-limo.limo.

With the new rule, if you write a problem `abcd.efgh.tex` that needs
an image `xyz.png`, the script generating that image should be
`abde.efgh.xyz.py`.

 ``Entirely in the garage'' is something of a trick question, since it
 means ``all of the limo is in the garage at same time'' and ``at the
