samples: big_http_download: make num_iterations unsigned
It is documented as unsigned in
samples/net/sockets/big_http_download/Kconfig
Signed overflow is undefined behavior, unsigned is not. This fixes the
following warning:
-Wstrict-overflow=1
samples/net/sockets/big_http_download/src/big_http_download.c:346:2:
In function 'main':
error: iteration 2147483648 invokes undefined behavior
[-Werror=aggressive-loop-optimizations]
346 | } while (--num_iterations != 0);
