strace: disable mpers (multiple personality) support on aarch64 to fix

https://hydra.nixos.org/build/69542376

[dezgeg: changed to --enable-mpers=check instead of --enable-mpers=no,
which makes it probe at build-time whether a certain personality is
supported and enable it only if the probe succeeded, instead of
unconditionally disabling it. Should be more future-proof.]
