Replace lost puppetdoc for home_dir_perms

[rjw1]

The documentation for this variable was lost in e15b4e3

@rjw1 This feature is actually being deprecated, but I didn't want to break functionality just yet (I believe that was my intent, anyway -- you can see that $home_dir_perms param is no longer passed through). Would that represent a problem for you?

[rjw1]

I do actually use home_dir_perms.
I hadn't realised that the behaviour had changed in that commit as well.
To be honest a breaking change would have been better than an option that does nothing or at least a warning message if its set to something other than the default.
I actually pin to a commit in my Puppetfile anyway so probably wouldn't notice.

Ok, I'll reverse course on that then, and restore functionality to that flag!

[rjw1]

Thanks 👍

@rjw1 Opened #54 to track the regression. I'm going to close this out, as there's more work to be done here than just restoring the docstring. Should have this resolved in a day or two.

Hmmm, I seem to have been on the wrong branch, docs seem to be the only missing piece here.
