check-webkit-style complains about anonymous blocks in C code

[Andy Estes]

When using an anonymous block in C code, such as:

dispatch_async(queue, ^{
    // anonymous block
});

check-webkit-style complains:

"Missing space before {  [whitespace/braces] [5]"

As far as I know our style guide doesn't cover blocks specifically, but this is a common style and should probably be allowed.

The patch in <https://bugs.webkit.org/show_bug.cgi?id=86411> has an example of such a block.

Should be too hard to fix the regex if it bothers you:

and add a corresponding test here:
