[Application] Fixed path of getAppSharedURI

[Application] Fixed path of getAppSharedURI

Application should return path to the 'shared' directory which follows
the description of 'shared' directory content available here:
https://developer.tizen.org/development/training/native-application/understanding-tizen-programming/file-system-directory-hierarchy

New application returns the path like:
sh-3.2# ls -al /opt/usr/home/owner/apps_rw/org.example.basic/shared/
total 20
drwxr-xr-x 4 owner  users        4096 Jul 18 13:06 .
drwxr-xr-x 5 owner  users        4096 Jul 18 13:06 ..
drwxrwsr-x 2 owner  system_share 4096 Jul 18 13:06 data
lrwxrwxrwx 1 app_fw app_fw         58 Jul 18 13:06 res -> /opt/usr/globalapps/org.example.basic/shared/res
drwxr-xr-x 2 owner  users        4096 Jul 18 13:06 trusted

Instead of the previous result:
sh-3.2# ls -al /opt/usr/globalapps/org.example.basic/shared/
total 12
drwxr-xr-x 3 tizenglobalapp root 4096 Jul 18 13:06 .
drwxr-xr-x 6 tizenglobalapp root 4096 Jul 18 13:06 ..
drwxr-xr-x 2 tizenglobalapp root 4096 Jul 18 13:06 res
