Bug 13583 - Able to view menu for Statistics even when user does not have permission

Added check for borrowers that stops the Statistics link being shown. This could be done through the css but that function currently appears to be broke

Testing Plan:

-Search for a patron with an account that does not have the 'borrowers' permission
*Statistics should not be seen in the menu.

-Change the accounts permissions so they have the 'borrowers' permission
*Statistics should be present in the menu.
