CORE-3008: includeAll uses full file path with 3.5.3 version

If we have relative path in includeAll (eg: <includeAll path="../y"/>) then absolute path is entered in FILENAME column of DATABASECHANGELOG table as of 3.5.3 version and this issue is blocking us from uptaking this version.

Please find attached the test case.

I tried to make a change in FileSystemResourceAccessor#list method. Could you please review if this is the way to go?
