Define otacerts.recovery

By removing `recovery_available` property from "otacerts" and
defining a dedicated recovery-specific module for "otacerts".
`recovery_available` property should be used to allow the reverse
dependencies recovery modules to depend on the module, not to
install the module to the recovery partition.
