As encfs does not support hard linking, the rename of the temporary
message file fails.
This is the only occurrence of hard linking in offlineimap and can be
fixed by using an atomic `os.rename` instead of `os.link`+`os.unlink`.
I have been using the attached patch for more than 1.5 years and have
never again had any problems with offlineimap on encfs.
