debug: do not install packages on riscv

a2b6085 ("debug: add all packages required for the collect-info to the Dockerfile")
breaks build for the riscv arch. For some unknown reason
many packets are missing for the alpine 3.18 for the riscv
architecture. In order not to break the build just don't
install them for the riscv.
