COMPAT: mmap error is not always returned in English

Fixes a build error from pandas-dev#12946
caused by mmap error being returned in Italian when
`LOCALE_OVERRIDE="it_IT.UTF-8"`. The test fails with:
`AssertionError: "Invalid argument" does not match "[Errno 22]
Argomento non valido"`    ```python          msg = "Invalid argument"
tm.assertRaisesRegexp(mmap.error, msg, common.MMapWrapper, non_file)
```    i.e. message is not being matched. Change to match the errno
instead as that's the same across languages.
