commit: 5cdda3425c added a new flag,
GET_SIGNING_CERTIFICATES to PackageManager for use with getPackageInfo
that returns the signing certificate history, including the current signer,
of the given package. This is intended to replace the existing
GET_SIGNATURES flag and corresponding field. The previous commit did not,
however, implement the read/write Parcelable methods so that this
information could be reconstructed client side. Implement those methods
to actually expose the new API.
Bug: 64686581
Test: Test app pull of PackageInfo with GET_SIGNING_CERTIFICATES succeeds.
