[PATCH 2/4] Test case of conditional dprintf

[Yao Qi <yao at codesourcery dot com>]

This is to test that dprintf works well with condition.  Since print
stuff in dprintf is implemented as commands, so there should be no
FAIL without patch 1/5 applied.

Note that this case is similar to

  PR 15179 - Dprintf interrupts execution when condition is false

but I am still unable to reproduce this PR.  dprintf-cond.exp can easily
extended to reproduce PR 15180 in next step.
