[PATCH v3 7/9] docker: Install toolchains on arm64 host

[Simon Glass]

Refactor the code to support downloading toolchains for arm64 as well as
x86_64

There doesn't seem to be an xtensa toolchain for arm64 at the same
location, so download that only on x86

Changes in v3:
- Add patch to install toolchains on arm64 host
