cbfstool: Add dummy vboot callback vb2ex_printf()

With CL:2084062, macro VB2_TRY() is introduced, which is used within
various vboot2 APIs such as vb2_hash_verify(). vb2ex_printf() is used in
this macro to print error messages, but it is not defined in cbfstool.
Therefore, this patch adds a callback function vb2ex_printf(). Since
vprintk() is required to implement vb2ex_printf() and it is not
implemented in cbfstool, this callback is currently added as a dummy
function. We also don't lose anything because no messages were printed
before CL:2084062.
