ibeacon 1.0.1 (new formula)

Add formula for Radius Networks iBeacon CLI. A utility for scanning and
transmitting iBeacon profiles over Bluetooth 4.0.

https://github.com/RadiusNetworks/ibeacon-cli

Updats based on feedback:

- Download code from tarball
- Prefer double quotes
- Fix test for version string
- Require mavericks (for CLPeripheral#identifier)

Note about testing:

There was some discussion about adding more thorough tests, that do
something a little more useful than print the version number, but this
command requires BLE hardware. Since the test bots are VMs or Mac Minis
that may not have that hardware it is hard to exercise that
functionality. If there is some functionality exposed through the CLI
that does not require bluetooth hardware then we should add tests for
that.
ibeacon: add 1.0.1 bottle.

Closes #30237.
