[testsuite] [riscv] limit vwaddsub-1.c to rv64
The desired vw{add,sub}.wx instructions don't come up on rv32 for the
first two functions, we get v{add,sub}.vx instead.
I suppose this is an oversight, and something about the test is meant
for rv64 only, but the fact that the instruction is spelled out in the
intrinsic name and a different instruction is generated suggests
something may be wrong after all.
I could use a pointer to specs for these intrinsics and instructions to
tell for sure, but a closer look from someone more familiar with them
would definitely be welcome.
Tested on x86_64-linux-gnu native, and gcc-14 target riscv{64,32}-elf.
Ok to install?

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
