What happened?

Description

When file.ctime metric is true, the resouce file_permissions does not show when it is a directory.
When you specify a * in the include, and there is a folder in the path, the resource does not indicate that it is a directory.

Steps to Reproduce

 filestats:
   include: /tmp/jocorrea/*
   metrics:
     file.mtime:
       enabled: false
     file.ctime:
       enabled: true
   resource_attributes:
     file.path:
       enabled: true

Expected Result

{file_name="dir_jocorrea", file_path="/tmp/jocorrea/dir_jocorrea", file_permissions="drwxr-xr-x"}
{file_name="file_jocorrea", file_path="/tmp/jocorrea/file_jocorrea", file_permissions="-rw-r--r--"}

Actual Result

{file_name="dir_jocorrea", file_path="/tmp/jocorrea/dir_jocorrea", file_permissions="-rwxr-xr-x"}
{file_name="file_jocorrea", file_path="/tmp/jocorrea/file_jocorrea", file_permissions="-rw-r--r--"}

In the actual result, the dir_jocorrea file_permissions do not display the d.
