Address a very theoretical possible security issue in mandos-client.

If there were to run some sort of "cleaner" process for /run/tmp (or
/tmp), and mandos-client were to run for long enough for that cleaner
process to remove the temporary directory for GPGME, there was a
possibility that another unprivileged process could trick the (also
unprivileged) mandos-client process to remove other files or symlinks
which the unprivileged mandos-client process was allowed to remove.
This is not currently known to have been exploitable, since there are
no known initramfs environments running such cleaner processes.

* plugins.d/mandos-client.c (main): Use O_NOFOLLOW when opening
                                    tempdir for cleaning.
