weston-terminal: Ignore SIGPIPE

This ensures that the default signal action doesn't kill weston-terminal
when the terminal tries to paste into a pipe whose read end has already
been shut down. (For example, a pipe from a misconfigured program or from
one which crashes/exits before the terminal calls write().)
