Use current direcotry instead of system tmp dir

Fixes #2

`sys_get_temp_dir()` could be avoided.
It potentially adds an unnecessary copy of the file between partitions
during the `rename()`, plus on Windows+IIS, it may lead to
permission/ownership issues.

Also added removing temporary file on failure.
