Fix Integration tests for Big endian on GA CI (#6720)

## What's the problem this PR addresses?

Fixes the GA CI Integration jobs failing for Big endian.


## How did you fix it?

1. Changed multiarch image to `tonistiigi/binfmt:latest` for running Big
Endian tests as the tests failed in `multiarch/qemu-user-static` image.
**Note:** All tests passed on s390x host VM, issues were seen in
`multiarch/qemu-user-static` image.
Tested running Integration tests using `tonistiigi/binfmt:latest` and
all Big Endian Integration tests have passed.

2. Increased `TEST_TIMEOUT` for Big Endian to fix TC's failing due to
timeout issue:
