Memcached: respect the end marker in the maximum supported length

The length in the "VALUE" line was accepted up to NGX_MAX_OFF_T_VALUE,
while ngx_http_memcached_filter_init() adds the size of the end marker
to it.  With lengths close to the maximum this overflowed u->length.

Now such lengths are rejected, similarly to other invalid lengths.
