axwrapper: Remove unused code resulting in warning.

axwrapper.c:49:13: warning: ‘sigchld_handler’ defined but not used [-Wunused-function]
static void sigchld_handler(int sig)
^~~~~~~~~~~~~~~
Since 71918b7d4e95 ("axwrapper: Mark functions sigchld_handler and
convert_{cr_lf,lf_cr} static.") made sigchld_handler() static gcc was
warning about the function being unused. No point in keeping this around;
SIGCHLD is perfectly fine.
Fixes: 71918b7d4e95 ("axwrapper: Mark functions sigchld_handler and convert_{cr_lf,lf_cr} static.")
