Subject: [PATCH] fix(@angular/build): apply define option to JavaScript from
 scripts option

The `define` option will now apply to JavaScript that is included in the output
via the `scripts` option.  This allows the replacement of identifiers within any
included scripts in addition to the already supported replacement within application
code.

(cherry picked from commit 5bd937b86e96f715e19cdf3517691ba2dfd133c8)
