restore SIGCHLD sighandler to default before spawning a program
From sigaction(2): A child created via fork(2) inherits a copy of its parent's signal dispositions. During an execve(2), the dispositions of handled signals are reset to the default; the dispositions of ignored signals are left unchanged. This refused to start directly some programs from configuring in config.h: static Key keys[] = { MODKEY, XK_o, spawn, {.v = cmd } }, }; Some reported programs that didn't start were: mpv, anki, dmenu_extended. Reported by pfx. Initial patch suggestion by Storkman.
