avcodec/tableprint: Don't include mem_internal.h

tableprint.h does not declare anything as aligned; it just prints
DECLARE_ALIGNED. So it can be removed; in fact, it needs to be removed,
because mem_internal.h includes config.h which leads to warnings when
building with hardcoded tables enabled because of redefinitions of
CONFIG_HARDCODED_TABLES.

(Furthermore, config.h is only valid for the target, not the host,
so HAVE_LOCAL_ALIGNED might even be wrong here.)
