docs: Changes the Kernel's /proc/self/status process name on Linux.
  
    The kernel name is NOT what will be shown by the ps or top command.
    It is a 15 character string stored in the kernel's process table that
    is included in the kernel log when a process is OOM killed.
    The first 15 bytes of name are used.  Non-ASCII unicode is replaced with '?'.
  
    Does nothing if /proc/self/comm cannot be written or prctl() fails.
  
    Args:
      name: bytes|unicode, the Linux kernel's command name to set.
