* gnu/packages/tex.scm (texlive-scripts): add mktexfmt

Hello. I have noticed while using a modular TeX Live installation that the texlive-scripts package
lacks mktexfmt, which is necessary for creating TeX fmts. TeX Live places mktexfmt in a
separate folder from the remainder of the scripts in this package, but mktexfmt is simply
a symlink to fmtutil, which is included in this Guix package. As such, this patch adds a phase to
the build system to create this symlink after fmtutil has been installed. An alternative solution would
be to add the mktexfmt file in the upstream TeX Live repository as a source location, but since that
file is still only a symlink to fmtutil, I believe it is easier to create the symlink ourselves as the package
is built. I apologize if there are any errors as this is my first patch.

Best,
Spencer
