[encrypted-media] Replace base64url values in examples with realistic values that use base64url-specific characters

ddorwin has just created a new issue for 
https://github.com/w3c/encrypted-media:

== Replace base64url values in examples with realistic values that use
 base64url-specific characters ==
https://w3c.github.io/encrypted-media/#clear-key and 
https://w3c.github.io/encrypted-media/keyids-format.html have examples
 that are supposed to contain unpadded base64url encodings 
([details](https://w3c.github.io/encrypted-media/index.html#using-base64url)).
 To better demonstrate base64url encoding (and provide values to be 
used in tests), the examples should demonstrate the absence of padding
 (where there could be padding) and the use of '-' and '_'. They 
should also have a realistic length (128 bits before encoding).

Note: The current example kid value of `"67ef0gd8pvfd0"`, which is 
invalid, appears to have come from [bug 
17682](https://www.w3.org/Bugs/Public/show_bug.cgi?id=17682#c6).
