Add OEM command to request flash size

The BMC flash is `/dev/mtd0` and the size can found in
`/sys/class/mtd/mtd0/size`. This OEM command will request that
information with MTDINFO.

Tested:
Successfully requested the flash size information with ipmitool.

```
cat /sys/class/mtd/mtd0/size
67108864
```
67108864 / 1024 / 1024 = 64MB flash

```
ipmitool raw 0x2e 0x32 0x79 0x2b 0x00 0x09
79 2b 00 09 00 00 00 04
```
Output in little endian.
0x04000000 -> 67108864

Add sys command for powercycle on host shutdown.

The new command will trigger a power cycle the next time the host shuts
down. This can exist in parallel with the existing mechanism to trigger
a power cycle after a specified time interval.

The implementation of host state detection and power cycling is platfrom
specific; the new command will just add a temporary file that marks the
system ready to powercycle on the next shutdown. Usually, a systemd unit
would be enabled by the presence of this file to handle the power
cycling process.
