Update setSystemSelectionChannels to use valid channels

-Rename the test RadioAccessSpecifiers so that it's
 clear that they are intentionally invalid due to
 the channel numbers being incorrect.

-Update the channels that will be used for setSystemSelectionChannels
 so that the channel numbers are valid. In addition, simplify the
 test so that it does not redundantly call the API if the op has
 already succeeded, and that it only attempts cleanup if there was
 a successful change.

-Allow a radio to return INVALID_ARGUMENTS to setSystemSelectionChannels
 in the event that neither of the requested bands are supported.
