[text] Crash when multi-byte utf8 text exceeds max_length

Bug 1500 - [Patch] clutter_text crash with non one-byte utf8 text exceed
           max_length

In clutter_text_set_text_internal(), when text length in character is greater
than max_length, and there are multi-byte character in it, then the new text
string buffer is not malloc()'ed with right length. This will cause the app to
crash with segmention fault.
