[Toybox] [PATCH] Clean warnings generated by scripts/genconfig.sh

[Georgi Chorbadzhiyski]

The attached patch prevents warnings related to clone flags. According
to clone(2) _GNU_SOURCE must be defined before including <sched.h>.

After the patch the following warnings disappear:

   <stdin>:2:11: error: 'CLONE_NEWNS' undeclared here (not in a function)
   <stdin>:2:23: error: 'CLONE_NEWUTS' undeclared here (not in a function)
   <stdin>:2:36: error: 'CLONE_NEWIPC' undeclared here (not in a function)
   <stdin>:2:49: error: 'CLONE_NEWNET' undeclared here (not in a function)
