ci/linker: update mold to 1.9

Bump needed for s390x fix with `-gsplit-dwarf` and `--gdb-index`.
See the https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/20435
for more details.

I also switched from make to cmake (make is unsupported now).

Additionally disabled build testing and enabled LTO build for Mold.
