efi_selftest: Add basic partition info check to block io test
Test the EFI_PARTITION_INFO_PROTOCOL in the existing EFI_BLOCK_IO_PROTOCOL
unit test. It is fairly basic, since it only checks that the values of the
struct efi_partition_info .revision, .type and .system fields are correct.
It doesn't check the MBR partition record information, because that's not
supported by the EFI_PARTITION_INFO_PROTOCOL implementation yet. The test
can be extended once the support is implemented, or if the in-memory disk
image used for the test is modified to have a GPT partition type instead.
