REGRESSION(276012@main): CMake fails with GObject-Introspection disabled
https://bugs.webkit.org/show_bug.cgi?id=269377

Reviewed by Michael Catanzaro and Philippe Normand.

* Source/WebKit/PlatformGTK.cmake: Quote the expansion of ${GI_VERSION}
  to ensure VERSION_GREATER_EQUAL has at least an empty string as value
  to compare against; otherwise when the variable is undefined there was
  no left-hand side of the comparison, which resulted in CMake erroring
  due to wrong syntax.
