[Bug-tar] [PATCH] xattr: fix compilation failure with -Werror

[Stefano Lattarini]

Without this change, building from the bootstrapped Git repository
with GCC (4.7.2) fails like this:

  xattrs.c:488:1: error: ‘xattrs__fd_set’ defined but not used \
    [-Werror=unused-function]
  cc1: all warnings being treated as errors
  Makefile:1305: recipe for target 'xattrs.o' failed

src/xattrs.c (xattrs__fd_set): Define this static function only if
the 'HAVE_XATTRS' preprocessor conditional is true.
