loader: Do not return OOM when layer count is 0

An application program that overrides malloc with an implementation that
returns NULL for a zero-sized allocation will cause some loader and
trampoline functions to incorrectly return VK_ERROR_OUT_OF_HOST_MEMORY
if there are no layers on the system. This patch prevents these errors
by also checking the layer count.

Fixes: https://github.com/KhronosGroup/Vulkan-Loader/issues/543
