makejdk.sh: replaced existing use of $VAR, ${VAR} and "${VAR}" with the respective versions depending on where the VAR was placed - use "$VAR" in if conditions - use ${VAR} is it was part of another string/variable i.e. "The source is ${VAR}" - use $VAR in all other circumstances

- use "$VAR" in if conditions
- use ${VAR} is it was part of another string/variable i.e. "The source is ${VAR}"
- use $VAR in all other circumstances

Note: ${VAR} is same as "$VAR", hence "${VAR}" is a bit overloaded
