terminal: Restore SIGPIPE to default

Prior to executing a new command make SIGPIPE to the default action as we normally disable to avoid. Otherwise we seem to be hitting a Broken Pipe message when running certain scripts.

This is similar to what other folks have been doing in https://github.com/labwc/labwc/issues/1209.

/cc @daniels or @derekf mind taking a look?

I'm wondering if we should instead store oldact at the time we first call sigaction() and restore it later, in case for some bizarro world reason whomever forked weston-terminal in the first place intentionally ignored that signal?

I'm kinda ok with that or your approach.

I'm vague on this, but I think you need to either initialize your sigaction to = { 0 }; or call sigemptyset on it before use though.
