os.totalmem() and os.freemem() return incorrect values

[johnottogood]

• Version: 6.14.3
• Platform: OS/390 MLZ1 26.00 04 2964
• Subsystem: os

The values returned by os.totalmem() and os.freemem() are very incorrect
On a z/OS 2.3 system system with 100GB of memory, this is what I get from the os calls:

/u/jgood> node

os.totalmem()
443241535480283100
os.freemem()
392770343992819840

Thanks @johnottogood. @ccw-1 recently spotted the same issue; the rcepool field we are dereferencing for the memory values should be treated as unsigned ints.

@joransiu will you or @miladfarca PR a fix, or can you point me at the code and I will?

Thanks @sam-github. @ccw-1 has reproduced and identified a prototype fix... looking for him to contribute.
