[Buildroot] [PATCH] package/dcron: create /var/spool/cron/cronstamps in installation

[unixmania at gmail.com <unixmania@gmail.com>]

From: Carlos Santos <unixmania@gmail.com>

The directory is required by dcron at run-time.

On systems with busybox and sysvinit startup /var/spool is a symlink to
/tmp (see package/skeleton-init-sysv/skeleton/) so the directories will
vanish after mounting /tmp, which by default is a tmpfs. In order to
really solve the problem we must also change skeleton-init-sysv to make
/var/spool persistent across rebuilds.

Fixes: https://bugs.busybox.net/show_bug.cgi?id=12011 (partially)
