sci-libs/coinor-clp: new EAPI=7 version 1.17.6.

Another "standard" version bump that is getting less standard. I've
added the usual coinor-* hacks and comments explaining them, but this
package is worse than some of the others. The mumps and libscotch
dependencies are being neglected in Gentoo, so a lot of that stuff is
broken. To work around it, we now require sci-libs/mumps (and
therefore sci-libs/scotch) to be built without USE=mpi.

I don't feel great about this ebuild, but it's a necessary step towards
a modern set of coinor-* packages that we can begin fixing in earnest.
