Simon Goldschmidt e30d50710d fuzz: allow overriding LWIP_RAND for fuzz tests
Fuzz tests need reproducible code, so we need an "unsafe" version of
LWIP_RAND() in this case...

Also, to reproduce fuzz tests cases from Linux on Windows,
LWIP_RAND_FOR_FUZZ_SIMULATE_GLIBC provides the first 20 random numbers that
glibc would have...
