If it isn't available in the system, we've got a fallback to
the normal localtime function, so normal code can assume it is
available as long as time_internal.h is included.

It should be forward compatible with newer freetype.

Include the freetype header, in-directly through a macro, like it
is done in the drawtext filter. Do not break if the header is moved.

Unfortunately the drawtext filter included the file where the include
macros are defined in a wrong way. This is not needed and breaks the
build. Remove that #include line too.
