fix(scripts/Dockerfile): create termux-packages repo directory hierarchy under /tmp so that TERMUX_PKGS__BUILD__REPO_ROOT_DIR validation does not fail in properties.sh file and export TERMUX_PKGS__BUILD__IS_DOCKER_BUILD to skip reading repo.json into variables

The `TERMUX_PKGS__BUILD__REPO_ROOT_DIR` validation checks if `scripts/properties.sh` file exists, which wouldn't exist under `scripts` directory if proper hierarchy is not created under `/tmp` directory.

Files above the `scripts` directory are not accessible during `cd scripts; docker build`, so `repo.json` cannot be copied to `tmp`, which is read by `properties.sh`. So skip reading its variables until it can be moved to under `scripts` directory in future during docker build.
