selftests/bpf: test_verifier verbose log overflows
Tests:
- 458/p ld_dw: xor semi-random 64-bit imms, test 5
- 501/p scale: scale test 1
- 502/p scale: scale test 2
fail in verbose mode due to bpf_vlog[] overflowing. These tests
generate large verifier logs that exceed the current buffer size,
causing them to fail to load.
Increase the size of the bpf_vlog[] buffer to accommodate larger
logs and prevent false failures during test runs with verbose output.
