selftests/ptrace: add test cases for dead-locks

This adds test cases for ptrace deadlocks.

Additionally fixes a compile problem in get_syscall_info.c,
observed with gcc-4.8.4:

get_syscall_info.c: In function 'get_syscall_info':
get_syscall_info.c:93:3: error: 'for' loop initial declarations are only
                                 allowed in C99 mode
   for (unsigned int i = 0; i < ARRAY_SIZE(args); ++i) {
   ^
get_syscall_info.c:93:3: note: use option -std=c99 or -std=gnu99 to compile
                               your code
