Fix _FORTIFY_SOURCE redefine error
If the _FORTIFY_SOURCE has been already defined, we shouldn't redefine
it, or it will raise a build error as below:
In file included from spice-audio.c:36:0:
../config.h:12:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
spice-audio.c:1:0: note: this is the location of the previous definition
