Allow apps to specify the target page size for aligning their
uncompressed shared libraries.
This allows apps that want to support larger page sizes to do
so by specifiying the -P <pagesize_kb> flag.
However, apps built for 4k-only devices are unaffected as they
can continue to use -p flag for 4kB page alignment of uncompressed
shared libraries.
