Don't throw for LazyValue in Parcel.hasFileDescriptors()

In aosp/1819733 we extracted Parcel.hasFileDescriptor() for types
produced by Parcel.writeValue() and consumed by Parcel.readValue() out
of Bundle into Parcel. It's supposed to handle LazyValue too.

However, we put a check to verify that it was a type supported by
readValue()/writeValue() by retrieving the VAL_XXX type of the value via
Parcel.getValueType(), however, that method throws for LazyValue since
we don't actually write that special type on the wire. However, we still
want Parcel.hasFileDescriptor() to support it, so moving the check into
a last 'else' statement, making sure we don't throw in case the value is
a LazyValue.
