RFR: 8298027: Remove SCCS id's from awt jtreg tests

[Jayathirth D V]

Noticed SCCS jtreg id's in 2 open awt tests. After jtreg 7.1 update, jtreg doesn't parse SCCS id's and it causes the tests with SCCS id's to fail.

As of now these 2 tests are ignored, but it is good to remove these SCCS id's.
If we don't need these 2 tests since they are ignored, then i will update the PR base on the review comments.
