pin version of angular/cli that is installed globally by Makefile.common

[Galen Charlton]

Angular 8.0 was released recently and requires newer versions of node and npm than what Evergreen currently uses. At present, angular/cli is installed globally as part of the install_developer Makefile.install option, which means that recent full builds of the Angular staff client started failing with errors like this:

Running ng build --prod:
You are running version v8.11.4 of Node.js, which is not supported by Angular CLI 8.0+.
The official Node.js version that is supported is 10.9 or greater.

Please visit https://nodejs.org/en/ to find instructions on how to update Node.js.
Return Value = 3

(see http://testing.evergreen-ils.org/~live/archive/2019-05/2019-05-29_16:00:03/test.29.html)

To avoid this, we need to pin the version of angular/cli that gets installed globally.

Thanks, Galen.

Patch tested and confirmed.

make -f Makefile.install ubuntu-xenial-developer installed ng-cli version 7.3.9 as expected.

Fix merged to 3.2 and above.
