[CK] Fix for hipblaslt error in PyTorch Dockerfile (#6537)

## Motivation
This PR fixes the hipblaslt client build failures that occur when
building the PyTorch Docker image, which are currently causing failures
in CI.

## Technical Details
- Correctly reset the working directory to tmp/
- Added --use-system-packages to the install.sh to use system installed
laplack packages, as hard-coded paths were not being built.

## Test Plan
Locally built the Docker image using the Dockerfile.

## Test Result
Image was successfully built.
