bpf.exp: tentative fix for bigmap1.stp hang on RHEL8

Experimentation with the prior bigmap1.stp patch
shows that bpf.exp may need a stronger kill -KILL to
avoid waiting for a stuck process.

Not sure why this wasn't done in the first place,
the comment suggests kill -KILL but the code does kill -INT.
