[Flatpak SDK] Adapt clean-webkit script to flatpak
Created attachment 407700 [details] Patch
This script, clean-webkit, is used by the EWS in the 'unapply-patch' step. See: https://ews-build.webkit-uat.org/#/builders/34/builds/4962 When passing the '--keep-jhbuild-directory' knob the script deletes everything inside 'WebKitBuild/' except 'DependenciesGTK/' and 'DependenciesWPE/'. Since the EWS bots are using Flatpak, the script removes everything inside 'WebKitBuild/' and the following step 'compile-webkit-without-patch' fails because libwpe dependency is missing.
