Currently, the page size and hugepage size have been statically defined. Post FEAT_LPA2, the Aarch64 Linux kernel adds support for 4k and 16k translation granules on higher addresses; we restructure the test to support the same. In addition, we avoid invocation of the binary twice, in the shell script, to reduce test noise.
