clients/simple-vulkan.c: fix find_memory_type()

Browse source 
- Use "<" instead of "<=" in the loop condition
- Remove `(1u << i) <= allowed` from the loop condition for simplicity
- Use `(...propertyFlags & properties) == properties` instead of
  `(...propertyFlags & properties)` to ensure all requested properties
  are present
