[bug#68296] [PATCH v3 2/2] gnu: Add klee.

[soeren]

From: Sören Tempel <soeren@soeren-tempel.net>

* gnu/packages/check.scm (klee): New variable.

Signed-off-by: Sören Tempel <soeren@soeren-tempel.net>

Changes since v2: Switch to a non-debug build-type to workaround an
internal error being triggered in clang while building KLEE with it.
