gcc-plugins: randstruct: Update code comment in relayout_struct()

Update code comment to clarify that the only element whose layout is not randomized is a proper C99 flexible-array member. This update is complementary to commit 1ee60356c2dc ("gcc-plugins: randstruct: Only warn about true flexible arrays")
