ansible_freeipa_module: Convert int to string in compare_args_ipa

With IPA 4.5 integers for examle in pwpolicy_find are returned as
integer values. The internally generated value will be converted from
integer to string (using to_text) if the value from find call result
is a string (or unicode for Python2).
