(wd-security) Update installer file location

[brogers5]

Description

This changeset updates wd-security's fileLocation variable in the install script to reflect a recent change in the upstream ZIP archive's directory structure.

Motivation and Context

wd-security was recently auto-updated to v2.1.3.304, and the resulting package that was pushed to the Community Repository has failed Package Verification testing, due to an outdated value.

How Has this Been Tested?

1. choco pack'd the resulting package while within the wd-security directory.
2. choco upgrade wd-security --source="'.'"
3. Confirmed the install script completed successfully.
