[LLVM] Mark reloc-none test unsupported on Hexagon

[mysterymath]

Prevents infinite loop issue recorded in #147427. More work will be required to make @llvm.reloc_none work correctly on Hexagon.

[llvm-ci]

LLVM Buildbot has detected a new failure on builder sanitizer-x86_64-linux running on sanitizer-buildbot1 while building llvm at step 2 "annotate".
