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.
