emmc-logger: Add timeout logic for stop logging
The caller of this script has a 90 second limit, and it is not
finishing in that window. This change defines what will happen in the
event that it takes longer to stop logging then expected.
Tested with psdmd timeout chnage
HOST:
```
emmc_tool --action=erase --erase_type=crypto_erase
(recovered with)
psdm StorageDeviceAction 'device_set: DEVICESET_ALL, initialize_action { properties {} }, psm_allow_list { value: ["bmc-psm"] }' --uid=
```
BMC:
```
cat /dev/random | systemd-cat
```
With this chnage the bmc does not have issues running the emmc_tool
command
