I guess, you're referring to those entries only, right?

Some of the tools you're using seems to use temporary mount points to do
stuff. No idea though, what program might be responsible for that.

You may specify (POSIX extended) regular expressions when specifying the
mount point: If the first *and* last characters are '/', then it's auto-
matically treated as a regex (if regex.h was available at compile time).
So, adding something like the following should do the trick:

  MountPoint "//tmp/.+/"

(the first and last '/' will be removed before compiling the regex)
