health: vendor.charger-* -> vendor.charger.

Browse Source 
Devices may have actions triggered by
init.svc.vendor.charger. If the name is changed,
these actions are not triggered properly.

The name is usually vendor.charger, so the default
service will also use vendor.charger as the name.

Test: none

Specifically:
* You may ignore the `service` line. The name of the service does not matter.
* For the `service` line, if the name of the service is **NOT**
`vendor.charger`, and there are actions
in the rc file triggered by `on property:init.svc.<name>=running` where
`<name>` is the name of your charger service, then you need a custom health
AIDL service.
* If your service belongs to additional classes beside `charger`, you need a
custom health AIDL service.
* Modify the `seclabel` line. Replace `charger` with `charger_vendor`.

It is recommended that you move the existing `service` entry with
`class charger` to the `init.rc` file in your custom health service.
If there are existing actions in the rc file triggered by
`on property:init.svc.<name>=running`, where `<name>` is the name of your
existing charger service (usually `vendor.charger`), then the name of the
service must be kept as-is. If you modify the name of the service, the actions
are not triggered properly.
Modify the entry to invoke the health service binary with `--charger` argument.
