MEDIUM: stick-table: allocate the table key of size buffer size

Keys are copied from samples to stick_table_key. If a key is larger
than the stick_table_key, we have an overflow. In pratice it does not
happen because it requires :
   1) a configuration with tune.bufsize larger than BUFSIZE (common)
   2) a stick-table configured with keys strictly larger than buffers
   3) extraction of data larger than BUFSIZE (eg: using payload())

Points 2 and 3 don't make any sense for a real world configuration. That
said the issue needs be fixed. The solution consists in allocating it the
same size as the global buffer size, just like the samples. This fixes the
issue.
