Make NIO Transport Services available on watchOS 6 (#47) 

Motivation:

With Network.framework becoming available on watchOS, you should now be
able to run your favourite NIO applications on watchOS 6!

Modifications:

Updated availability annotations to allow NIO TS.

Result:

More NIO on more watches
