Symlinks in encrypted folder

[beornf]

During running the gocryptfs set of benchmarks I noticed the following error:
UNTAR: tar: linux-3.0/arch/microblaze/boot/dts/system.dts: Cannot utime: No such file or directory

This seems to be due to the target of symlinks being encrypted in a different way to encfs. This is an example to reproduce in a mounted folder:
touch test; ln -s test symlink; touch -h symlink; No such file or directory

Thanks for the report! This also has a testcase now: 8f1e517
