Add SUPReMM ETL framework to Open XDMoD package

[jtpalmer]

The SUPReMM ETL framework was previously included in the SUPReMM Open
XDMoD module package.

Description

Changes build configuration to include the SUPReMM ETL framework in the Open XDMoD package.

See ubccr/xdmod-supremm#40

Motivation and Context

What is referred to here as the SUPReMM ETL framework is not specific to SUPReMM and is considered part of the base Open XDMoD package. Therefore, it should be packaged as such.

Tests performed

Installed Open XDMoD and the SUPReMM module before and after this change. Compared both installations to ensure that all the same files are installed. Also compared contents of tarballs before and after the changes to ensure the files were present where expected.
