sci-mathematics/flint: new EAPI=7 revision.

This new revision is based off François Bissey's ebuild in the
sage-on-gentoo overlay, which has accrued some fixes not present in
the ::gentoo version. Of note, it fixes an open build bug, and an
unreported issue where 32-bit libraries are detected on a 64-bit
system.

The update to EAPI=7 required only moving the LaTeX dependencies to
BDEPEND. In the process, I updated the LICENSE to LGPL-2.1+ because
upstream has done the same. I also looked long and hard for a reason
why we have RESTRICT=mirror in the ebuild. Finding none, I have
removed the restriction.
