[PATCH 1/1] sbsigntool: add support for RISC-V images

[Heinrich Schuchardt <heinrich.schuchardt@xxxxxxxxxxxxx>]

The UEFI 2.9 specification defines:

    EFI_IMAGE_MACHINE_RISCV32 = 0x5032
    EFI_IMAGE_MACHINE_RISCV64 = 0x5064

The same values can be found in the PE-COFF specification. Cf.
https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#machine-types

    IMAGE_FILE_MACHINE_RISCV32 = 0x5032
    IMAGE_FILE_MACHINE_RISCV64 = 0x5064
