Pedro Alves 2de900d8ff Test interrupting programs that block SIGINT [gdb/9425, gdb/14559]
This adds a couple testcases that exercise interrupting programs that
block SIGINT.  One tests a program that uses sigprocmask to mask out
SIGINT, and the other tests a program that waits for SIGINT with
sigwait.  On GNU/Linux, it is currently impossible to interrupt such a
program with Ctrl-C, and you can't interrupt it with the "interrupt"
command in all-stop mode either.

These currently fail, and are suitably kfailed.  The rest of the
series will fix the fails.

Tested on GNU/Linux native, gdbserver, and gdbserver + "maint set
target-non-stop on".
