debug/tst-longjmp_chk2: Make signal handler more conservative [BZ #20248]
Currently, printf needs more stack space than what is available with
SIGSTKSZ. This commit use the the write system call directly instead.
Also use sig_atomic_t for the “pass” variable (for general
correctness), and restore signal handlers to their defaults, to avoid
masking crashes.
