[OE-core] [PATCH] mdadm: fix systemd service start up failure

[changqing.li at windriver.com]

From: Changqing Li <changqing.li at windriver.com>

1. mdadm: No mail address or alert command - not monitoring

with --monitor mode, mdadm needs a mail address and/or a program.
This can be given with "mailaddr" and "program" lines to that
monitoring can be started using.

fix by given a mail address, user can replace with a valid one
when use.

2. cannot create pid file: No such file or directory

fix by create dir before starting.
