Makefile: generated yacc/lex/gperf source are maintainer-clean

Those files should not be cleaned using the standard distclean or clean
rules, because they "may require special tools to rebuild" and thus
should be kept, especially in released tree.

They should only be removed inmaintainer mode (but a "git clean -dX"
will remove them too!).
