[PATCH v3 0/2] Check if extra_modules is modified rather then always rebuild

[Kairui Song]

Update from V2:
  - Improve the error message
  - Also check module dependencies
  - Clean up code

Update from V1:
  - Update check_files_modified instead of introduce a new function
  - Give proper message when invalid/builtin module name is given
  - Behave properly with weak-modules

Kairui Song (2):
  kdumpctl: follow symlink when checking for modified files
  kdumpctl: don't always rebuild when extra_modules is set
