RFR: JDK-8189324: install-file macro no longer handles files with $ in them

[Erik Joelsson]

In my recent change for JDK-8189095, I changed the quoting of all src 
and targets files in the install-macros from single to double. I did 
this in an early version of that patch to allow for the shell to match 
the ? wildcard. In the final version of the patch, I instead use 
explicit subst of ? to space so there is no need for the shell to expand 
wildcards. This makes the change of quotes unnecessary.

Worse is that changing to double quotes has now made the shell expand 
strings like "$1" in file names, which typically occurs with anonymous 
inner classes in Java. This causes both intermittent build errors as 
well as prevents files with $ in them from being copied.

This patch restores the double quotes to single quotes.
