check-webkit-style is wrong about expected format for std::function variables

[Brady Eidson]

check-webkit-style is wrong about expected format for std::function variables.

Seen in the patch(es) attached to https://bugs.webkit.org/show_bug.cgi?id=124698 -

Source/WebKit2/Shared/AsyncRequest.h:60:  Extra space before ( in function call  [whitespace/parens] [4]
Source/WebKit2/Shared/AsyncRequest.h:78:  Extra space before ( in function call  [whitespace/parens] [4]
Source/WebKit2/Shared/AsyncRequest.h:89:  Extra space before ( in function call  [whitespace/parens] [4]


The lines in question are:
    static PassRefPtr<AsyncRequest> create(std::function<void (Arguments...)> completionHandler)
    AsyncRequestImpl(std::function<void (Arguments...)> completionHandler)
    std::function<void (Arguments...)> m_completionHandler;

The style-checker needs to know that when "something that looks like a function decl/def" is inside std::function<> brackets, the space before the paren is expected.
