Flymake correctly highlights whole last line if eob (bug#29201)

If a line/column pair indicates an end-of-buffer position, flymake
should behave like the case where the last line of the buffer is
referenced without a column indication.  This behavior is currently
to highlight the whole last line.

* lisp/progmodes/flymake.el (flymake-diag-region): Correct
conditions of fallback to the fallback-eol local function.
