[https://nvbugs/6401925][fix] Unwaive DeepSeek V4 compressor corner-case test

[yuxianq]

Summary by CodeRabbit

• Tests
  • Removed one test skip entry, allowing that previously waived integration test case to run again.

Description

Remove the DGX B200 waiver for
test_prefill_corner_cases[overlap_large_head_dim] from waives.txt.

The test passed 100 consecutive fresh-process runs on a DGX B200 after a clean
B200 build, so the failure tracked by https://nvbugs/6401925 was not reproduced.

Test Coverage

• Waiver parser: parsed all 626 remaining entries successfully.
• python scripts/check_test_list.py --validate: 2371 unique entries validated.
• DGX B200 at commit 0e9c8fb7cb0467bfcc0284d1f5354cc6115baecd:
  exact test selector passed 100/100 consecutive runs.
