sci-libs/mumps: new revision to fix more underlinking.

When building without USE=mpi, the various lib*mumps libraries use
LAPACK symbols without actually linking to liblapack. There are
already a bunch of hacks in the mumps ebuild to work around these
issues, so all I've done is add one more. As a simple test case,
you can try to run the test suite for sci-libs/coinor-clp with
USE="mumps metis", which now works.

Closes: https://bugs.gentoo.org/777840
Package-Manager: Portage-3.0.20, Repoman-3.0.3
