Add recovery_available to cc_genrule

recovery_available property is required in cc_genrule. Specifically,
we will mark libminijail as recovery_available:true as part of building
adbd and other stuffs for recovery. Some source code of libminijail is
created via cc_genrule, so we need recovery_available in the module
type.
