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 agent-msg-filter.c:21:0:
../config.h:17:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
agent-msg-filter.c:1:0: note: this is the location of the previous definition
