[PATCH 0/1][groovy:linux-aws] Remove an unused file

[Tim Gardner]

[Impact]

debian.aws-20.10/scripts/helpers/copy-files is unused and can be confusing,
especially for derivatives.

The eye of Sauron (in the form of apw) has cast its baleful glare on
this bit of cruft.

[Test Plan]

Perform a successful build

[Where problems could occur]

Any regressions will be noted at build time.

[Other Info]
