work around linux bug in readlink syscall with zero buffer size
linux fails with EINVAL when a zero buffer size is passed to the syscall. this is non-conforming because POSIX already defines EINVAL with a significantly different meaning: the target is not a symlink. since the request is semantically valid, patch it up by using a dummy buffer of length one, and truncating the return value to zero if it succeeds.
