6.3.0.0.beta2: calendarImpl: name clash

[balducci@xxxxxxxx]

hello

apparently due to 942de6a01ba990e5f3bc55ce4ab3737a03f67f39, 6.3.0.0.beta2 build
stops for me with:

AFAICS, Locale and Calendar clash w/ corresponding declarations in
headers from icu4c (64.2).

As a matter of fact, the following fixes the build for me
