ICU-13483 Use a real time zone to make tests work in Android.

When running in Android, java.util.TimeZone.getDefault() will only
return a TimeZone object for a time zone that actually exists, so when
passing a bogus test TimeZone object to setDefault() and afterwards
calling getDefault() it won't return that same time zone.

Changing our tests to instead use a real existing (but otherwise unused)
time zone instead makes the tests work in Android as well.

Neither of these tests was testing the ability to set an arbitrarily
made up time zone as the default, so no test coverage is lost.
