stdlib: Let filelib:find_source() search subdirs
The Design Principles states that an application can have Erlang
source files one level below the "src" directory, and now
filelib:find_source() by default searches one level below "src".
The same applies to "esrc". That directory is only mentioned in
filename(3).
