hk: Use rowPitch from VkImageDrmFormatModifierExplicitCreateInfoEXT

Imported linear images may have an arbitrary row pitch. As long as it is
aligned to 16 agx can support. Initialize `.linear_stride_B` from the
supplied parameter and let ail verify it.

Fixes gtk dmabuf based tests with a pitch aligned to 256.
