csplit: don't prematurely terminate cleanup (Bug#9076)
* src/csplit.c (interrupt_handler): Reset signal to SIG_DFL
after deleting the files, so that a second interrupt won't
prematurely terminate cleanup.
(main): Don't use SA_NODEFER | SA_RESETHAND, as that might
allow premature termination of cleanup. Also, this ports better
to platforms like NonStop, which don't ahve SA_RESETHAND.
