Well, I am no expert in MIDI, so anyone correct me if I am wrong, but to my
knowledge lilypond doesn't contain any soundfont at all. The MIDI-files
generated by Lilypond are just played via the GM-Standard Soundfont that
comes with your operating system.

I suggest you to take a look at the file drumpitch-init.ly in
usr\share\lilypond\current\ly of your Lilypond directory and analyze it
until you understand what it does. Part of it is described here:
http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Common-notation-for-percussion#Custom-percussion-staves

I don't work with MIDI output but I believe if you make your custom
drum-pitch tables you can alter the midi-drumpitch table accordingly, you'll
just have to know which MIDI-representation each sound of your soundfont has
and later make sure that your MIDI-file is played back using your djembé
soundfont.

I hope this was of some help.

Regards,
Tao
