[collectd] [BUG + patch] Collectd::Unixsock.pm sends too long messages

[Pavel V.]

 Hi, Collectd community.

 After my upgrade I found an issue, what collection3 FLUSH does not work on some graphs.

 I got the following message in my webserver logs about this:

   index.cgi: FLUSH failed: Parsing options failed. at ../lib/Collectd/Graph/Common.pm

 While debugging I found what unixsock.c plugin has limited buffer size of 1024 bytes when reading
 received data, but Collectd::Graph::Common::flush_files() and Collectd::Unixsock::flush() tries to
 flush all files at once, which results to excessive data being sent via socket. This ends by error
 message which is described above.

 I'm glad to propose a patch to fix this issue, see attached file.

 Thanks.
