[PATCH v2 1/2] bpf, test_run: Replace hardcoded page size with dynamic PAGE_SIZE in test_run

[Saket Kumar Bhaskar]

Replace fixed value 4096 with PAGE_SIZE for calculating the max_data_sz
in bpf_prog_test_run_xdp, which allows for a more accurate determination
of max_data_sz, considering different default page sizes across different 
architectures.
