As documented in mkdir()'s manpage, the mask specified has umask
applied on it. If the specified mode is more restrictive than umask it
will win, thus mode should first be set to permissive, e.g. 0777, and
then umask will work.

Adding umask as configuration option is slightly harder but should be
easy looking at how other global options are defined.
The change you listed as one-liner looks good to me, just check the
rest of collectd code for more mkdir() invocations and send the patch
(which you can obtain it with `git patch --path-with-stat` if you
previously cloned git repo)
