Ralph Giles 8efa019f44 Bug 1253762 - Adapt texttrack_chrome to work with e10s. r=kinetik
Convert this to a plain mochitest so it runs in the client context,
and use the SpecialPowers object's wrap() and unwrap() methods to
access the privileged parent pointer api.

Rename _chrome to _moz to clarify that this is a moz-specific
extension, since chrome privilege is ambiguous in the context
of e10s.
