[disco:linux-azure, xenial:linux-azure][PATCH 1/3] UBUNTU: SAUCE: sgx-update: Add script to fetch SGX from Intel repo

[Marcelo Henrique Cerri]

BugLink: https://bugs.launchpad.net/bugs/1844245

Add a script to simplify the process of fetching the new version of
the SGX driver source code.

The user is still responsible for reviewing the new changes and
tagging the commit with a proper launchpad bug.
