tests: fix tests in go1.22 (go-delve#3583)

Go1.22 has changed some line number assignments. The new line number
assignments are still valid however some tests in dap relied on them
being different and broke as a result. This commit fixes those tests
and makes them less brittle.
Also disables TestDebugStripped and TestDebugStripped2 temporarily on
1.22.
