[ticket/12133] fix download file names for WebKit-derived browsers

All browser engines that descend from WebKit declare themselves as Safari in the user agent, including Chrome. Currently, the code assumes that any Safari-like browser cannot handle the RFC-compliant filename syntax. At least for recent versions of Safari, this is no longer the case, and the legacy syntax results in URI-quoted filenames. Using the standard syntax works as expected in both Safari 9 and Chrome 45. The ticket reporting this issue is from January 2014, so we can safely ignore compatibility: any browser still relying on the previous behaviour is unlikely to receive security updates. PHPBB3-12133
