package/qt5/qt5webkit: fix JavaScriptCore parser error

qt5webkit build currently fails with the following error:

This issue is due to =~ being marked as deprecated since a few Ruby
versions, and finally removed in 3.2.0 [1]. This now breaks the build since
buildroot has moved to Ruby v3.3.0.
The corresponding fix has already been issued in upstream Webkit project
[2], but qt5webkit version tracked in buildroot does not have the
corresponding webkit version pulled. Fix this build error by bringing the upstream
patch. The patch is slightly modified (exclude part about Changelog file,
which is absent from qt5webkit)

+ https://bugs.webkit.org/show_bug.cgi?id=206233
+
+Reviewed by Yusuke Suzuki.
+
+Avoid a warning about using Object#=~ on Annotation instances, which
+has been deprecated in Ruby 2.7.
+
+* offlineasm/parser.rb: Swap checks to prevent applying the =~ operator
+to Annotation instances, which do not define it.
