    base-files: add some safety checks in profile
    
    Add some safety checks when sourcing files in /etc/profile.d/, in particular:
    - source only *.sh files, not every file. This is the practice in use in both
      Fedora and Debian/Ubuntu (see
      https://help.ubuntu.com/community/EnvironmentVariables#A.2Fetc.2Fprofile.d.2F.2A.sh);
    - check the input is actually a file and is readable. This check is especially
      important if profile.d is empty, as "*.sh" will get expanded only if
      profile.d is not empty. Previously if profile.d was present but empty,
      "/etc/profile.d/*" was sourced causing errors on login and breaking stuff, for
      example X startup.
