Fix test_regrtest when run with uops always on

[gvanrossum]

The fix has two parts:

• When -X uops is detected, pass it on to the subprocess created to run the manufactured test.
  I need this so I can run ./python -Xuops -m test test_regrtest and see it fail without the next fix.
• Use -R 6:3: in ArgsTestCase.test_huntrleaks instead of -R 3:3: -- it takes longer to settle with -X uops.

(This is an attempt to make gh-107820 pass all tests. The other failure there is an failing assertion in test_exceptions, but I believe that's fixed by gh-108725.)

Just gonna merge.
