browser: select an inaccessible directory also when tabbed

When the user tab-completed a name at the Go To Directory prompt, this
name will end in a slash.  Remove this slash, so the name can be found
in the file list (where directory names don't include the final slash).

This fixes http://savannah.gnu.org/bugs/?48353.
