geo-rep: Fix syncing of symlink
Problem:
If symlink is created on master pointing
to current directory (e.g symlink -> ".") with
non root uid or gid, geo-rep worker crashes
with ENOTSUP.
Cause:
Geo-rep creates the symlink on slave and
fixes the uid and gid using chown cmd.
os.chown dereferences the symlink which is
pointing to ".gfid" which is not supported.
Note that geo-rep operates on aux-gfid-mount
(e.g. "/mnt/.gfid/<gfid-of-symlink-file>").
Solution:
The uid or gid change is acutally on symlink
file. So use os.lchown, i.e, don't deference.
