pg_upgrade:  quote directory names in delete_old_cluster script

This allows the delete script to properly function when special
characters appear in directory paths, e.g. spaces.

Wouldn't single quotes be better than double quotes if you want to
defend against special characters?

I thought of that.  Windows only does double-quotes, I think, and I
didn't see any value to doing a platform-specific quoting.  Do you?

All of our makefiles use single quotes, so effectively the only
character we don't support in directory paths is the single quote itself.

This seems to say that Windows batch files don't have any special
meaning for single quotes:

http://stackoverflow.com/questions/10737283/single-quotes-and-double-quotes-how-to-have-the-same-behaviour-in-unix-and-wind

Again, is it worth doing something platform-specific?  I can certainly
define a platform-specific macro for " or ' as and use that.  Good idea?
