reintroduce jpeg files invalidly removed in 01aa38

During the original generation of 01aa38, jpeg was removed.  This
broke things, thus was removed from that patch- unfortunately the files
still were removed.

Restore them from 01aa38^.

resolved breakage in http://build.chromium.org/p/chromiumos/builders/chromiumos%20sdk/builds/719/steps/BuildBoard/logs/stdio

BUGS=None
TEST=emerge jpeg
