gst1-validate: disable building documentation using sphinx

Fix a build failure in case (a non functional) sphinx documentation
system is installed on the host (reported [1] and fix tested [2]
by grunpferd@netscape.net).

Fixes:

  sphinx-build -b html -d ./doctrees   . ./html
  Error: Source directory doesn't contain a conf.py file.

[Arnout:
 - use --disable-sphinx-doc instead of a cv variable
 - remove the comment, it speaks for itself]
