Feature Request: Update agent-install.sh to support the RISC-V microprocessor architecture

[johnwalicki]

Is your feature request related to a problem? Please describe.

As discussed on the July 29 Open Horizon TSC meeting, Intensivate and others are interested in Open Horizion support of RISC-V. The agent-install.sh script will need to be modified.

Describe the solution you'd like.

Add riscv64 as a valid microarchitecture. Likely initially using Debian but potentially Fedora has RISC-V rpms available too.

Describe alternatives you've considered
