sway: restore SIGPIPE handler before exec:ing swaybar
Sway ignores SIGPIPE (by installing a SIG_IGN handler), in order to
“prevent IPC from crashing Sway”.
SIG_IGN handlers are the *only* signal handlers inherited in
sub-processes. As such, we should be a good citizen and restore the
SIGPIPE handler to its default handler.
