Get the maximum PID value.
On Linux, the value is read from the `/proc/sys/kernel/pid_max` file.
From `man 5 proc`:
The default value for this file, 32768, results in the same range of
PIDs as on earlier kernels. On 32-bit platfroms, 32768 is the maximum
value for pid_max. On 64-bit systems, pid_max can be set to any value
up to 2^22 (PID_MAX_LIMIT, approximately 4 million).
If the file is unreadable or not available for whatever reason,
returns None.
Some other OSes:
- On FreeBSD and macOS the maximum is 99999.
- On OpenBSD >= 6.0 the maximum is 99999 (was 32766).
- On NetBSD the maximum is 30000.
