flush: Detach mime data

Browse source 
Drawing directly to a surface has to be surrounded with cairo_surface_flush()
and cairo_surface_mark_dirty().

However, if the surface has mime data associated, this would hit the following
assert:

lt-cairo-test-suite: cairo-surface.c:1381: cairo_surface_mark_dirty_rectangle:
Assertion `! _cairo_surface_has_mime_data (surface)' failed.

This is now fixed by detaching all mime data in cairo_surface_flush().

Fixes: create-from-png, create-from-png-stream
