David Windsor 5166973b20 selftests/x86: Add shadow stack uprobe CALL test
Add coverage for entry uprobes installed on CALL instructions while user
shadow stack is enabled. The test puts an entry uprobe on a helper whose
first instruction is a relative CALL, then verifies that the call/return
sequence completes without SIGSEGV.

This catches regressions where x86 uprobe CALL emulation updates the
regular user stack but leaves the CET shadow stack stale.
