dev-perl/Bio-SamTools: Add fixed version for bug #661112

- Reworked patches so the autodetection stuff is nixed, because its
  really silly and doesn't work.
- Paths now computed in ebuild and passed explicitly
- Fix handling of libdir for lib64 re bug #661112, but in a different
  way than proposed by Sławomir Nizio, mostly because I didn't see that
  suggestion until after I'd done all my changes (but also because
      relying on a hardcoded path in the code is also fragile)
- Converted to EAPI7
- Removed unused empty variable assignments
