Subject: [PATCH] sysupgrade: add missing _GNU_SOURCE define (FS#2469)

Fixes compilation problems:

error: implicit declaration of function 'asprintf'; did you mean 'vsprintf'?
[-Werror=implicit-function-declaration]
   57 |   if (asprintf(&name, "%s%s", prefix, blobmsg_name(option)) <= 0)
      |       ^~~~~~~~
      |       vsprintf
