sci-libs/fplll: new version 5.3.2.
This new version is based on François's v5.3.1 ebuild in the
sage-on-gentoo overlay. I investigated adding support for the
sci-libs/qd package, but the build system is a bit weird about it at
the moment, so ultimately there's only one important change: I've
bumped the subslot to match the first component (6) of the soname.
The EAPI was also updated to 7 uneventfully.
