Evgenii Stepanov found a bug where argv0len was set wrong for threads
(no /proc/$PID/cmdline so setting was skipped and previous value retained), which led to memcpy() with an overlapping source/dest range (annoying asan). Fix: move temp variable and assignment outside the if() statement so we assign zero if we can''t read the file.
