refactor(provisioning): make scripts self-locating and read configs locally

All provisioning scripts and modules now resolve their own location via
BASH_SOURCE and derive PROJECT_ROOT_PATH from it, removing a hard
dependency on the current working directory.

- Derive PROJECT_ROOT_PATH/CONFIGFILES_PATH/MODULES_PATH/SCRIPTS_PATH
  from BASH_SOURCE in SetupNewSystem.sh and every module
- Replace all curl ${DL_ROOT}/... downloads with cat of the matching
  local files under ProjectCode/ConfigFiles (the dl.knownelement.com CDN
  is no longer required for a git clone)
- Invoke modules by absolute path instead of cd ./Modules/X && bash ./x
- Fix secharden-audit-agents.sh: wrong path depth (../../ vs ../../..),
  wrong Project-Includes glob, and ConfigFiles/AudidD -> AuditD typo,
  all of which previously crashed the script
- Remove duplicate FrameworkVars source lines

Run from anywhere with: sudo bash ProjectCode/SetupNewSystem.sh
