test: rng: Add a UT testcase for the rng command
The 'rng' command dumps a number of random bytes on the console. Add a
set of tests for the 'rng' command. The test function performs basic
sanity testing of the command.
Since a unit test is being added for the command, enable it by default
in the sandbox platforms.
