Reviewed by Simon Fraser.

This patch aligns WebKit with Gecko / Firefox, Blink / Chromium and Web-Spec [1].

"If the attribute is not specified, then the effect is as if a value of 'translate'
were specified".

This PR changes default value from 'SVG_TRANSFORM_UNKNOWN' to
'SVG_TRANSFORM_TRANSLATE'.
