reuse util.is_fileobject

Browse Source 
is_fileobject usgae was removed due to the use of the `tell` method check.
This change remove this check wich allows us to completely test if
fileno() is usable. Also it handle most of the exceptions around created by
breaking changes across Python versions. Hopefully we are good now.

fix #1174
