signal/signalfd: Add support for SIGSYS
I don't know why signalfd has never grown support for SIGSYS but grow it now.
This corrects an oversight and removes a need for a default in the
switch statement. Allowing gcc to warn when future members are added
to the enum siginfo_layout, and signalfd does not handle them.
