vnc: tight: specific zlib level and filters for each compression level

Disable png filters for lower compression levels. This should lower
the CPU consumption and reduce encoding time.

This isn't in tight_conf because:
  • tight_conf structure must not change, because it's shared with other
    tight implementations (libvncserver, etc..).
  • it'd exceed the 80 col limit.
  • PNG_ macros are only defined if CONFIG_VNC_PNG is defined
