Subject: [PATCH] tools lib api: Use -D_FORTIFY_SOURCE=2 for non-debug builds

Commit 58b79186c343 ("tools lib api: Fix make DEBUG=1 build") intended
to drop -D_FORTIFY_SOURCE=2 for debug builds. It did that, but also
degraded -D_FORTIFY_SOURCE=2 to -D_FORTIFY_SOURCE (which implicitly
defines the symbol to 1), probably by mistake. Add the =2 back.

Fixes: 58b79186c343 ("tools lib api: Fix make DEBUG=1 build")
