pkg/system: move CheckSystemDriveAndRemoveDriveLetter to pkg/archive
This one is a "bit" fuzzy, as it may not be _directly_ related to `archive`,

// This is used, for example, when validating a user provided path in docker cp.
// If a drive letter is supplied, it must be the system drive. The drive letter
// is always removed. Also, it translates it to OS semantics (IOW / to \). We
// need the path in this syntax so that it can ultimately be concatenated with
// a Windows long-path which doesn't support drive-letters. Examples:
// C: --> Fail
// C:\ --> \
// a --> a
// /a --> \a
