Change SigAction::flags to use from_bits_truncated #869

  1. Change SigAction::flags to use from_bits_truncated 

    On Linux, if the signal trampoline code is in the C library, sigaction
sets the SA_RESTORER flag (0x04000000) in the sa_flags field of old
sigaction (see sigreturn(2)).

This is not intended for application use and is missing from SaFlags,
therefore from_bits fails and unwrapping panics the user program.

This fix just drops the bits that are not defined in SaFlags.
