Packaging improvements for RHEL and SLES

- Properly honor --prefix in build system and rpm spec file.
- Add '--define require_kdir' to spec file to support building
  rpms against kernel sources installed in non-default locations.
- Add '--define require_kobj' to spec file to support building
  rpms against kernel object installed in non-default locations.
- Stop suppressing errors in autogen.sh script.
- Improved logic to detect missing kernel objects when they are
  not located with the source.  This is the common case for SLES
  as well as in-tree chaos kernel builds and is done to simply
  support for multiple arches.
- Moved spl-devel build products to /usr/src/spl-<version>, a
  spl symlink is created to reference the last installed version.
