Fix duplicate uniformBufferStandardLayoutFeatures
Fix duplicate uniformBufferStandardLayoutFeatures

When constructing the linked list for the
vkGetPhysicalDeviceFeatures2 there were two entries for
VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_UNIFORM_BUFFER_STANDARD_LAYOUT_FEATURES_KHR
inserted, and done in such a way that there was a loop
in the linked list. This caused vkGetPhysicalDeviceFeatures2
to hang.

The problem appears to come from the master->vulkan-cts-next-dev
merge 00d76712b6c78401dd07b5268a569775eef9fbbe.

Affects:

dEQP-VK.* (but you only need to run one test)
