[PATCH] Allow /tmp to be a symlink to /run/tmp

[Serge Belyshev]

Hi! This patch fixes two small issues:

In /usr/share/doc/initscripts/README.Debian it is documented that /tmp
could be a symlink to a non-existent directory, which will be created.
However, this fails because bootclean.sh runs before mountall.sh and
clean_tmp() chokes on a broken link.

Shortly thereafter, mount_tmp() fails to create the directory with the
proper mode.  Fixed thus.
