efl: simplify automake.

efl: simplify automake.

Instead of -I$(top_srcdir)... -I$(top_builddir)... and then do it for
the .la, use the EFL_ macros to generate the contents to be used in
automake files.

There is a nasty bit that libtool will parse Makefile*.am and will not
get _DEPENDENCIES from _LIBADD and _LDADD if these are in
@REPLACEMENT@. To solve this we must explicitly set _DEPENDENCIES. The
contents of this is almost the same as _LIBADD or _LDADD with the
"_INTERNAL_" replacement name.

I hope the code will be result will be shorter and consistent as there
is less places to change when we add/remove dependencies.

Statistics are quite impressive (diffstat):
