import-checker: force 'fcntl', 'grp', 'pwd', and 'termios' to stdlib modules

These are Unix only, and caused these additional warnings on Windows if they
aren't hardcoded as stdlib:

  mercurial/posix.py mixed imports
     stdlib:    errno, getpass, os, socket, stat, sys, tempfile
     relative:  grp, pwd, unicodedata
  mercurial/posix.py mixed imports
     stdlib:    re
     relative:  fcntl
  mercurial/posix.py mixed imports
     stdlib:    array
     relative:  termios

Additionally, this was missing on Windows:

  mercurial/crecord.py mixed imports
     stdlib:    fcntl, termios
     relative:  curses
