  1. src: check size of args before using for exec_path 

    If we are in an artifically created Environment that has no args set,
and uv_exepath returns an error (for instance, if /proc is not mounted
on a Linux system), then we crash with a nullptr deref attempting to
use argv[0].

Fixes: nodejs#45901
