This reorders the code in the 32-bit vDSO images to put the signal trampolines first and __kernel_vsyscall after them. The order does not matter to userland, it just uses what AT_SYSINFO or e_entry says. Since the signal trampolines are the same size in both versions of the vDSO, putting them first is the simplest way to get the addresses to line up. This makes it work to use a more compact layout for the vDSO.
