java: make the syntax error format string translatable

The error format should be translated, but contrary to the case of
C/C++, we cannot just depend on macros to adapt on the
presence/absence of '_'.  Let's consider that the message format is to
be translated iff there are some internationalized tokens.

* src/output.c (prepare_symbol_names): Define b4_has_translations.
* data/skeletons/java.m4 (b4_trans): New.
* data/skeletons/lalr1.java: Use it to emit translatable or not the
format string.
