Update code path for all applications that have new versions in a release

If a new version of an application did not include any erlang module
changes, the code path of the application was not updasted unless a
'load_object_code' instruction was added for the application. This
would be a problem if e.g. only some files in the priv dir were
changed, since calls to code:lib_dir or code:priv_dir would then point
to the old location of the application. This has been corrected - now
code:replace_path/2 will be called for all applications that are
changed (i.e. when the application's vsn is changed in the .rel file).
