update_chroot: install standard toolchains all the time

We've been installing & updating the subset of toolchains needed by a
board to save on space & time.  Unfortunately, that doesn't work well
in the Rust world which needs all the toolchains installed before it
can update itself.

Since we have no way out of this, and most devs will most likely have
either half if not all of these installed on their system overtime,
just flip it to install all of them.  Our SDK is already including
these too, so it's not much of a change anymore.

Basically this means we'll require these all be installed:
aarch64-cros-linux-gnu
arm-none-eabi
armv7a-cros-linux-gnueabihf
armv7m-cros-eabi
i686-cros-linux-gnu
x86_64-cros-linux-gnu

In total, they currently take up ~3GB of disk space.

BUG=None
TEST=CQ passes
