explicitly call ::bind to distinguish from std::bind

We have |using namespace std;| in this file and that seems to cause
conflicts in the GCC used on the Travis CI build machines when resolving
|bind|.  Attempt to fix this by explicitly picking which |bind| we're
calling.
Add new __kernel_vsyscall() offset seen in linux 3.15.3.
