Implement makedirs in file.managed.
use func_alias for makedirs, lint fixes

This commit changes makedirs() to makedirs_() and makes a func_alias, so
that the makedirs params don't override them. It also makes several lint
fixes that clean up unused variables, replaced built-ins, etc.
Pass makedirs to file.managed, file.serialize states

Also some lint fixes, and since states modules aren't supposed to
directly make changes, two calls to os.makedirs() have been replaced.
Cleanup call to file.check_managed

This function no longer contains a makedirs param, so remove it.
fix error message when no changes made
