[Patch testsuite] Change xfail conditions for bb-slp-34.c

[James Greenhalgh]

Hi,

ARM and AArch64 will still vectorize bb-slp-34.c - we're not operating
with a cost model so we vectorize to a 64-bit vector of two ints, and the
permutes are just element swaps.

So, don't mark this test xfail for arm/aarch64.

Checked on x86_64-none-linux-gnu, arm-none-eabi and aarch64-none-elf with
no issues.

OK?

Thanks,
James
