dev-util/Tensile: fix compilation of sci-libs/rocBLAS on gfx906

Clang-20 disallowed op_sel in some VOP3P dot instructions.
See: llvm/llvm-project#100485

As ROCm maintains a fork of Clang, these changes did not reach official ROCm releases.
However Gentoo uses original Clang-20, which has these incompatible changes.
Luckilly, in Tensile these op_sel do nothing. Generally, they allow to shuffle vector elements before multiplication, but with values 0,0/1,1 shuffling is disabled and op_sel can be removed.
