jifmux: Detect EOI correctly
...
EOI are not always at the last 4 bytes. We need to search
the last 5 bytes to find the 0xFFD9 sequence as jpegenc seems
to round the buffer size to the next 4 multiple.

jifmux: Avoid recombining RGB jpegs
...
JFIF only allows YUV as colorspace, when we receive an RGB jpeg,
we should just push it forward without adding the JFIF marker.

Revert "jifmux: Merge xmp and tagsetter tags."
...
This reverts commit 4e5c412234
.
jifmux shouldn't be able to handle jif and shouldn't expect
any xmp on its data. So, no need to handle them.
