Deal with ../logs existing, and log not being a symlink

The rails-post-deploy script would error if the log directory existed
(rather than being a symlink to another directory, for example) and
the ../logs directory also existed.  This commit changes this
behaviour to move the existing log directory out of the way in this
case.

In addition, this commit switches from removing the old symlink and
creating a new one (which creates a gap in time during which the log
directory doesn't exist) to using "ln -snf" to just overwrite any
existing symlink or file.  (Note that this is still not an atomic
operation, but it's bound to leave less time between removal and
creation.)
