* test_recovery_sigint: Ensure precondition is met
test_recovery_sigint depends on its process has SIG_DEF sigaction for
SIGINT. When its parent process set SIG_IGN which inherits to children,
then this test fails. This patch ensures this precondition met
regardless of inherited sigaction from its parent.
* Add test for restoration of other SIGINT handlers
Add another variant of test_recovery_sigint to ensure IRB to preserve
existing SIGINT handler other than SIG_DEF.
