Update library packaging: split to slop and libslopy

Two things have been changed in upstream: build system now properly
places 64-bit .so under %{_libdir}, and the .so itself now contains
versioned SONAME.

This means we can remove workaround for the first issue and start
packaging library separately.  This is much closer to FPG than before.
