selftests/bpf: Double the size of test_loader log 

Testing long jumps requires having >32k instructions. That many
instructions require the verifier log buffer of 2 megabytes.

The regular test_progs run doesn't need an increased buffer, since
gotol test with 40k instructions doesn't request a log,
but test_progs -v will set the verifier log level.
Hence to avoid breaking gotol test with -v increase the buffer size.
