[tex-live] failure to build mptopdf.fmt

[Jonathan Kew]

After the latest update to context/base/supp-pdf.tex in texlive, the  
mptopdf format will no longer build.

This is because it no longer loads supp-mis.tex, but the supp-mpe.tex  
module that is loaded after supp-pdf still requires this (and doesn't  
check or load it).

A simple patch to allow mptopdf.fmt to build would be:

But Hans may wish to do something entirely different with it.
