map: use giterr_set internally

Edward Thomson · Edward Thomson · commit 04c3b35f9c90 · 2016-02-23T13:08:50.000-05:00
Use the `giterr_set` function, which actually supports `GITERR_OS`.
The `giterr_set_str` function is exposed for external users and will
not append the operating system's error message.
