LibJS+LibTimeZone: Explicitly canonicalize "GMT" to "UTC"

Browse source 
This is a normative change in the ECMA-402 spec. See:
50eb413

Note that this canonicalization already occurred. As the above commit
alludes to, we parse the rearguard format of the TZDB, so GMT is already
an alias to Etc/GMT. But it doesn't hurt to be explicit here.
