Of course it helps if we spell the name right...

Subject: remote.c: spell __attribute__ correctly

We want to tell the compiler that error_buf() uses
printf()-style arguments via the __attribute__ mechanism,
but the original commit (3a429d0), forgot the trailing "__".
This happens to work with real GNUC-compatible compilers
like gcc and clang, but confuses our fallback macro in
git-compat-util.h, which only matches the official name (and
thus the build fails on compilers like Visual Studio).
