[PATCH] ramfs needs to update directory m/ctime on symlink

ramfs neglects to update the directory mtime and ctime fields when creating
a new symbolic link.  Ramfs was modified in 2.6.15 to update these fields
when other types of entries are created.  The symlink support is separate
from that other support, so that change did not cover quite all of the
possibilities.

All of the directory content manipulation entry points now seem to be
covered with respect to these time field updates.
