adhd: seccomp: allow faccessat/2 syscalls
Starting with glibc 2.33 the faccessat syscall will be used
more consistently accross architectures so we need to add
them to arm and amd64 in addition to arm64.
Starting with glibc 2.33 faccessat2 is also preferred and
checked for ENOSYS even though it might not exist on older
kernels so we need to allow it as well on all archs.
Example failures:
comm="cras" exe="/usr/bin/cras" sig=0 arch=c000003e
syscall=269 code=0x7ffc0000
comm="cras" exe="/usr/bin/cras" sig=0 arch=c000003e
syscall=439 code=0x7ffc0000
BUG=b:187795855
TEST=Local builds; CQ.
