autofs-5.1.4 - fix directory create permission

From: Ian Kent <raven@themaw.net>

autofs mount point directory creation is done using a permission of
0555.

But it is necessary to create directories within autofs mount points
for some map entry types so write access should be set for the owner
on mount point directories.
