Makefile: add -Wformat-security to CFLAGS

Browse Source 
Apparently when travis checks patches, it compiles code with
-Wformat-security (most probably because the distro/gcc it uses
has it on by default), but on my system (Fedora 24/gcc 6.1.1)
this flag is not on. As a result, code compiles fine for me
but travis reports an error.

Add -Wformat-security to default CFLAGS. It helps to catch
problems like using printf(str) instead of printf("%s", str).
