sci-libs/rocBLAS: fix tests using openblas as cpu reference

Add a patch that classify 6 test suites as known_bug.
Upstream will fix this issue in future releases,
and they recommand this as solution for current version.

+Those tests will fail comparing rocblas vs openblas, because the testing program is so strict that it cannot tolerate the numerical differences which is actually OK.
