meson: fix warning for bad sphinx-build
The warning was printing an empty string if the bad sphinx-build was not passed on the command line. Instead, always use the path that was returned by find_program. Reported-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
