dialyzer: fix bug concerning compiler option 'warnings_as_errors'
A typical scenario: the type digraph() is used in R16 (compilation
with the option 'warnings_as_errors' results in no warning); then the
module is analyzed by a 17 Dialyzer where digraph() is obsolete, and
since the warning is turned into an error Dialyzer fails to load the
module.
Thanks to Michael Truog.
