Simplify and robustify code_server:all_loaded/1

The main ets table kept by code_server contains several pieces
of information. Therefore, code_server:all_loaded/1 need to
filter the information in the table.

code_server:all_loaded/1 can be simplified if we use
ets:select/2. Currently, the filtering is done by filtering
away unwanted stuff ({sticky_dir,Mod} tuples). It is more
robust to filter on the stuff that we want to keep
({Mod,Path} tuples, where Mod is an atom) in case that we'll
add more auxiliary records to the table later.
