gsi_util: refactors Checker and VintfChecker

This change includes several refactoring:
  1. Adds more function/class comments.
  2. Renames the fields in namedtuples 'CheckListItem' and 'CheckResultItem'.
  3. Fixes the vintf check issue. It should do two checks:
     system -> vendor and vendor -> system, instead of one direction.
  4. Fixes import statements, should only import module or package name.
  5. Use python3-style print() function instead of print statement.
  6. Fix the missing 'import errno' in image_mounter.
  7. Checks *.py under 'checker' folder can pass 'pylint'.
     Disables the check for a given line if it cannot pass.
     e.g.,  pylint: disable=too-few-public-methods
  8. Changes 'summary' result from a string 'pass' to '#pass/#total'.
