[CMake] check-webkit-style provides bogus explanation for alphabetical sorting error

[Michael Catanzaro]

In https://bugs.webkit.org/show_bug.cgi?id=144747#c5

check-webkit-style claims:

ERROR: Source/WebKit2/PlatformGTK.cmake:491:  Alphabetical sorting problem. "PluginProcess/PluginControllerProxy.cpp" should be before "PluginProcess/EntryPoint/unix/PluginProcessMain.cpp".  [list/order] [5]

There really is an alphabetical sorting problem on line 491:

list(APPEND WebKit2_SYSTEM_INCLUDE_DIRECTORIES
    ${WTF_DIR}
    ${CAIRO_INCLUDE_DIRS}

But I have no clue where PluginProcess/PluginControllerProxy.cpp and PluginProcess/EntryPoint/unix/PluginProcessMain.cpp are coming from. Those have nothing to do with this.

Also on https://bugs.webkit.org/show_bug.cgi?id=145408#c9

It complains about an alphabetical sorting error on Source/WebCore/PlatformEfl.cmake.

While this error is true, it was not caused by my patch. It was already there and my patch don't touches any line near it. So it shouldn't complain about something unrelated with the patch.

But these entries aren't in these lines, but
- 484 instead of 366
- 495 instead of 378
- 501 instead of 383
- 509 instead of 391
- 514 instead of 396

The difference is 118 everywhere, I have no idea why.
Let me check it to try to find where the bug is.

The bug is in _check_list_order, line_number isn't incremented when matched is true. We should use enumerate to avoid this kind of bugs.
