Is there a reason we don't distribute libjpeg?

This is clearly GPL-compatible. Furthermore, libjpeg is incredibly stable, with its last release in 1998, and tiny at 599k. Is there some issue with it that I don't know about?

There used to be a huge *patent* issue with the algorithms that resulted in
multimillion dollar lawsuits. Then a champion of open source came and
saved the day (look it up) :-). Now that patent stuff is gone.
libjpeg is not in Sage only because nobody has needed it yet. I made
an experimental spkg for it a long time ago -- it's called libjpeg-6b.spkg
and it's listed under experimental spkg's.
