Auto merge of #3496 - Takashiidobe:fix-typos, r=JohnTitor

fix typos in libc

Fixing some typos:

For the change in `src/unix/bsd/apple/mod.rs`, I don't think changing the name of a param changes ABI so I think it's safe to change, but could be wrong. I believe the correct spelling is here: https://opensource.apple.com/source/Libc/Libc-498/darwin/libproc.c.auto.html which indicates it should be `minor`.
