[PATCH bpf-next 3/3] selftests/bpf: Update expected output for sub64_partial_overflow test

[Puranjay Mohan <puranjay@kernel.org>]

Update the expected regex pattern for the sub64_partial_overflow test.
With BPF_SUB now supporting linked register tracking, the verifier
output shows R3=scalar(id=1-1) instead of R3=scalar() because r3 is
now tracked as linked to r0 with an offset of -1.
