selftests/bpf: Sanitize pointer prior fclose()
There are scenarios where env.{sub,}test_state->stdout_saved, can be
NULL, e.g. sometimes when the watchdog timeout kicks in, or if the
open_memstream syscall is not available.
Avoid crashing test_progs by adding an explicit NULL check prior the
fclose() call.
