Allowing GSI patch level to be greater than vbmeta SPL

The GSI patch level might be greater than the vbmeta SPL, because
GSI system.img might be updated via the DSU flow, where vbmeta.img won't
be updated in this scenario.

Allowing GSI patch level to be greater than or equal to the vbmeta SPL,
since Treble allows new system.img works on old vendor images.
