Add riscv64 systems to spread tests

[imatrisciano]

This PR adds RISCV 64 systems to the spread test systems pool.

As of right now, the only ubuntu versions with RISCV64 qemu images available in image-garden are Ubuntu Cloud 24.04 and Ubuntu Cloud 26.04

To run spread tests targeting the newly added riscv64 systems, make sure the required qemu-riscv64 component is installed:

sudo snap install image-garden+qemu-riscv64 # for riscv64 emulation

Then, use the following to run all riscv64 tests:

SNAP_CHANNEL=edge image-garden.spread -v -vv ...riscv64

Due to delays caused by emulation, #372 might be required to make some tests pass (like update_policy)

[farshidtz]

$ SNAP_CHANNEL=edge image-garden.spread ...riscv64

@farshidtz thank you for testing, are you able to provide the complete logs while running tests in verbose mode?

Also please make sure that the qemu-riscv64 component is installed:

$ sudo snap install image-garden+qemu-riscv64 # for riscv64 emulation

[farshidtz]

Thanks, it runs as expected after installing the qemu-riscv64 image-garden component:

$ sudo snap install image-garden+qemu-riscv64
component qemu-riscv64 10.2.1 for image-garden v0.5 installed
