Sergei Trofimovich 2a9fc04635 cc-wrapper/add-hardening.sh: always unset _FORTIFY_SOURCE before re-setting it 
On darwin clang driver always sets -D_FORTIFY_SOURCE=0 under asan.
This causes -Werror to trip over macro redefinition:

    <command line>:1:9: error: '_FORTIFY_SOURCE' macro redefined [-Werror,-Wmacro-redefined]
    #define _FORTIFY_SOURCE 2
            ^

To avoid it let's always explicitly undefine it first before redefining.
