valgrind: Do not use outline-atomics on aarch64

This avoids the __getauxval undefined reference error seen with gcc10 on
doing static linking with -nodefaultlibs, which is uncommon usecase
anyway, disabling outline-atomics is not a huge deal for OE in terms of
performance as we already use -mcpu which is tuned enough to the SOC the
code is being generated for
