ref-manual: Updated bitbake/ section to remove wrapper script
Robert P. J. Day noted that the bitbake command no longer uses a wrapper as the section indicated. I have removed this reference. Reported-by: Robert P. J. Day <rpjday@crashcourse.ca> (From yocto-docs rev: ccdcf3d80f2e684877265d2dde8606ddeed4dfd2) Signed-off-by: Scott Rifenbark <scott.m.rifenbark@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
