Profiles example has bad copy because buffer is not large enough

[spencer-lunarg]

The profiles demo on RADV looks like this

With

Validation Error: [ VUID-vkCmdCopyBufferToImage-pRegions-00171 ] | MessageID = 0x6f4d3c00
vkCmdCopyBufferToImage(): pRegions[0] is trying to copy 16 bytes + 0 offset to/from the (VkBuffer 0x210d07000000003a) which exceeds the VkBuffer total size of 8 bytes.
The Vulkan spec states: srcBuffer must be large enough to contain all buffer locations that are accessed according to Buffer and Image Addressing, for each element of pRegions (https://docs.vulkan.org/spec/latest/chapters/copies.html#VUID-vkCmdCopyBufferToImage-pRegions-00171)
Objects: 2
    [0] VkCommandBuffer 0x58293520cef0
    [1] VkBuffer 0x210d07000000003a

The following change fixes it because the create_staging_buffer is doing sizeof(VkDeviceSize) underneath and is only creating an 8 byte buffer instead of 16 like it should
