efi_selftest: implement exception test for sandbox

Provide a unit test that causes an illegal instruction to occur.

The test can be run with the following commands:

    => setenv efi_selftest exception
    => bootefi selftest

This might be the output:

    Executing 'exception'
    EFI application triggers exception.
    Illegal instruction
    pc = 0x1444d016, pc_reloc = 0xffffaa078e8dd016
    UEFI image [0x0000000000000000:0xffffffffffffffff] '/\selftest'
    UEFI image [0x000000001444b000:0x0000000014451fff] pc=0x2016 '/bug.efi'
    Resetting ...

It would tell us that the exception was triggered by an instruction
0x2016 bytes after the load address of the binary with filename /bug.efi.
