rust-chg: remove SIGCHLD handler which won't work in oxidized chg
Since pager is managed by the Rust part, the C code doesn't know the pager
pid. I could make the Rust part teach the pid to C, but still installing
SIGCHLD handler seems horrible idea since we no longer use handcrafted
low-level process management functions.
Instead, I'm thinking of adding async handler to send SIGPIPE at the exit
of the pager.
