[kvm-unit-tests PATCH 3/4] riscv: sbi: Prefix several environment variables with SBI

[Andrew Jones <andrew.jones@xxxxxxxxx>]

Unit tests will likely share the environ so prefix variables that
are specific to specific tests to avoid polluting the name space.
We don't prefix generic stuff since they could be used by any test.
