Implement decoding of signal masks associated with signalfd file descriptors
When signalfds are used, normal signal handling method is usually
disabled, leaving strace without signals to catch and decode.
This patch adds decoding of signal masks associated with signalfd file
descriptors.
Decoding the signalfd_siginfo struct requires additional work mentioned
in github#199.
