unfs3: Fix utime for symlink in attr.c
unfs3 has an old defect that it can not change the timestamps of a symlink file because it only uses utime(), which will follow the symlink. This will not cause an error if the symlink points to an existent file but can be triggered with rpm workflows. Making unfs3 support lutimes() addresses this problem.

4Subject: [PATCH] attr: fix utime for symlink
5
6unfs3 has an old defect that it can not change the timestamps of a
7symlink file because it only uses utime(), which will follow the
8symlink. This will not cause an error if the symlink points to an
9existent file. But under some special situation, such as installing
10a rpm package, rpm tool will create the symlink first and try to
11modify the timestamps of it, when the target file is non-existent.
12This will cause an ESTALE error. Making rpm tool ignore this error
13is a solution, but not the best one. An acceptable approach is
14Making unfs3 support lutimes(), which can modify the symlink file
15itself. Considering not every system support this function, so a
16function checking is necessary.
