selftests/bpf: Update qemu config for riscv64 in vmtest.sh
When running vmtest.sh on riscv64, the kernel panic at boot due to an
illegal instruction. This is because '-cpu rv64' only enables a baseline
set of riscv extensions, whereas the kernel or toolchain requires newer
extensions. Switch to '-cpu max' so qemu enables all supported
extensions, and bump the required qemu version accordingly.
Additionally, qemu's pmu emulation for riscv64 currently has issues,
causing perf_event_open-related tests to fail. Temporarily disable the
sscofpmf extension to bypass these failures for now, and will try to
investigate and address it later.
While at it, update the libbpf/ci branch in INDEX_URL from 'master' to
'main'.
