Title: Depends on system icucore instead of icu4c formula.

* Follow upstream convention.

The original formula will result in binaries reference ``` `brew --prefix`/lib/libicuuc.50.1.dylib``` instead of icu4c in its prefix or opt_prefix. Since icu4c is keg_only, it will cause failure to find the dylib in runtime. Not sure how that happens.

Also, I see no reason not to follow upstream to use icucore.
