Fix 1bpp Xservers on "whitePixel=0, blackPixel=1" VRAMs.

- Don't override pScreen->blackPixel and pScreen->whitePixel
  (set in MD server Init functions per -filpPixels option)
  on 1bpp servers in merged fbSetupScreen() (merged one
  from cfbSetupScrenn and mfbSetupScreen() in old xsrc/xfree)
- Pull mfbCreateColormap() function from old xsrc/xfree tree
  and use it on 1bpp servers

Required by forthcoming X11R7'fied ancient Xsun and XsunMono servers:
 https://mail-index.netbsd.org/port-sun3/2020/07/17/msg000157.html

Without these fixes, mouse pointers and twm window titlebar etc. are
rendered inverted.

Pull 1bpp server fixes from xorg-server.old:
https://mail-index.netbsd.org/source-changes/2020/07/18/msg119488.html

Confirmed on luna68k 1bpp Xorg 1.20 server using xf86-video-wsfb
with "-flipPixels" option.
