Fix double close in NativeLibraryHelper.openApkFd.

Prior to this patch, we were taking the file descriptor owned by a
ParcelFileDescriptor, and passing it into ZipFileRO::openFd, which
expects to take ownership of the file descriptor, closing it upon
destruction. This leads to a double-close when the ParcelFileDescriptor
tries to close itself. Switch to passing a duped copy of the file
descriptor to ZipFileRO::openFd.

Test: `pm install foo.apk` with fdsan
