Proprietary Broadcom WiFi drivers are not compiled and loaded when installing Ubuntu MATE with proprietary drivers enabled

[Aaron Rainbolt]

Hardware: HP Elitebook 8570p, UEFI, no secure boot, Broadcom WiFi, 16 GB RAM, 120 GB SSD, 3rd Gen Intel Core i5.

Steps to reproduce:

1. Flash the latest daily image of Ubuntu MATE Lunar to a USB drive.
2. Boot a laptop with Broadcom WiFi from the drive.
3. Select "Try or Install Ubuntu MATE" at the GRUB menu.
4. Click "Install Ubuntu MATE".
5. Accept all default settings until you reach the "Installation type" screen.
6. Check the box to install proprietary drivers.
7. Proceed to the next screen.

Expected result: ubuntu-drivers should be run in the background, detecting the WiFi chipset and installing the needed bcmwl-kernel-source driver. WiFi should become enabled when this happens, while still in the live ISO session.

Actual result: ubuntu-drivers runs for a very short time according to the installer screen, then the next screen appears and WiFi is still disabled.

Booted from an Ubuntu Desktop Legacy ISO, and ran "ubuntu-drivers devices" and "ubuntu-drivers list" to get more info.

(Note that I typed these across since the live env didn't have Internet access, if I messed something up I'll go get an Ethernet cable and try again with termbin.)
