  1. cmd/snap-seccomp: add copy_file_range to syscallsWithNegArgsMaskHi32 

    While the base seccomp template only compares the sixth argument to 0,
the argument is a 32-bit "unsigned int". The high half of the register
won't necessarily have been cleared, so we want the same
CompareMaskedEqual behaviour.
