Adds ptrace_scope and timeout options to 17.1, tested working
Also adds hardened_malloc to 15.1, but failing to compile:
external/hardened_malloc/h_malloc.c:1688:18: error: use of undeclared identifier 'M_PURGE'
if (param == M_PURGE) {
^
external/hardened_malloc/h_malloc.c:1743:30: error: missing field 'ordblks' initializer [-Werror,-Wmissing-field-initializers]
struct mallinfo info = {0};
