clang-format/java: Allow one-line empty functions.

clang-format/java: Allow one-line empty functions.

Before:

    void f() {
    }
    int g() {
        return 0;
    }

Now:

    void f() {}
    int g() {
        return 0;
    }

Do this by removing the explicit setting for AllowShortFunctionsOnSingleLine,
as of recently [1] it defaults to "Empty" for Java, a new setting that does
what we want.

Chromium style used to unconditionally override AllowShortFunctionsOnSingleLine
to the wrong thing, so I taught clang-format to not do that for Java files, and
while there also made -style=Chromium do the right thing for most of the
settings [2], so remove most explicit settings from this file. Except for
AllowShortFunctionsOnSingleLine, this doesn't change behavior.

Make sure to grab the new binary from my home dir, else this patch will regress
stuff quite a bit :-)
