support/testing/tests/boot/test_grub.py: new test for RISCV64 EFI

Browse Source 
Commit f439b47ed "boot/grub2: add RISC-V 64bit EFI support" [1]
introduced the grub2 RISC-V UEFI support.

At that time, it was not possible to have a runtime test for this.
qemu-system-riscv64 is not in the Buildroot Docker reference image,
and the base distribution (Debian 11) does not provide a
sufficiently recent version. A qemu-system-riscv64 >= 8.0.0 is needed.

Commit 0d4177598 "support/testing/infra/emulator.py: add build host
dir to qemu search path" [2] added the capability to use the
Buildroot host-qemu package inside runtime test.

With this support, it is now possible to add a runtime test for a
grub2 UEFI boot on RISC-V 64bit.

Also, due to an upstream edk2 git submodule issue, this commit
includes a workaround to use https://sources.buildroot.net for this
test. See [3].
