package/x11vnc: drop unrecognized options

--without-{jpeg,sdl,zlib} are unrecognized since bump to version
0.9.14 in commit aeea662fb12e69073a233fe1058287212fbbca33 and
https://github.com/LibVNC/x11vnc/commit/d287ed9a77c647f35e85e0b10621a6661e911fad
because those dependencies were linked to libvncserver, not x11vnc

Fixes: aeea662fb12e69073a233fe1058287212fbbca33
