[Buildroot] [git commit branch/next] support/docker: add qemu-system-misc for riscv runtime tests

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=93c7b55c778e3dd4d84945918e5d97d5f56256c5
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

The docker image currently contains qemu-system-arm and
qemu-system-x86. Each package contains the 32bit and 64bit variants.
This has been sufficient for the time being.

The RISC-V ecosystem is growing rapidly. It is starting to become
mainstream. To increase the diversity in Buildroot runtime tests,
this commit adds the qemu-system-misc package in the Docker image,
in order to have the commands qemu-system-riscv{32,64}. This package
also contains other architectures (for example: microblaze, nios2,
s390x, xtensa, ...).
