Fix to allow the lua self-tests to work.

Note that the proper solution is to fix:

  19661394 ferror differences between Ubuntu and Solaris.

but until that happens, we can comment out a couple of asserts when trying to
read from a file that has been opened in "w" mode.

Note that we cannot apply this patch with all the other lua patches at
"gmake prep" time, because the lua tests are a separate download that's
only unpacked when we are actually testing the component.

This patch will not be sent upstream.

In order to generate consistent output from the lua tests, we need to
remove the writing of a '.' to stderr (to show progress).

This change will not be passed upstream.
