selftests/bpf: Fix sk_bypass_prot_mem failure with 64K page
The current selftest sk_bypass_prot_mem only supports 4K page.
When running with 64K page on arm64, the following failure happens:
...
check_bypass:FAIL:no bypass unexpected no bypass: actual 3 <= expected 32
...
#385/1 sk_bypass_prot_mem/TCP :FAIL
...
check_bypass:FAIL:no bypass unexpected no bypass: actual 4 <= expected 32
...
#385/2 sk_bypass_prot_mem/UDP :FAIL
...
Adding support to 64K page as well fixed the failure.
