Create a shim apk which is malformed

This shim-apk will be embedded in an apex to test out scenarios where
apk-in-apex fails to install.

Since this shim-apk is malformed, PackageManager will fail to parse it.
Hence it should not be possible to install this app at all. Hence I did
not add the hash of this shim-apk inside the manifest of shim-apk-v1
that comes pre-installed with device.

Bug: 152021141
Test: builds succesfully
Test: adb install CtsShimTargetPSdk.apk (fails to parse)
