Fix memory leaks in platform/image-encoders/JPEGImageEncoder.cpp

https://bugs.webkit.org/show_bug.cgi?id=118781

Reviewed by Brent Fulgham.

We can find the function "jpeg_finish_compress" call the function "jpeg_abort" at the end.
And the comments of "jpeg_abort" is "Abort processing of a JPEG compression operation,
but don't destroy the object itself". (We can find these in the "jcapimin.c" of jpeg)
So the compression object destroy need be called.
No new tests because this doesn't change functionality.

* platform/image-encoders/JPEGImageEncoder.cpp:
(WebCore::compressRGBABigEndianToJPEG):
