virgl: honor host caps in shader cash sha evaluation
This is needed because when we switch between GLES and GL on the host,
we have to lower atomics to ssbo, and with that the shaders can't be
pulled from the cache anymore. Likewise when we move the disk image with
a shader cache to a different host, other features might change that
will need lowering. To avoid using stale shaders in this case, merge the
caps into into the shader cache sha.
