extract_utils: template: use quotation marks and variable curly braces consistently

* This makes sure that multi-word arguments are passed correctly from
  extract-files.sh towards the common extract_utils helper. An example
  would be extract-files --section "Hello World".
* IMPORTANT: device repositories that use a device/common split
  typically do something like this to invoke the common script from the
  device one:

  ${MY_DIR}/../common/extract-files.sh $@

  This is incorrect because the quotation marks are missing, and will
  lead to incorrect parameter parsing. The correct way is:

  ${MY_DIR}/../common/extract-files.sh "$@"

* The curly braces are only for cosmetic consistency.
