Subject: selftests/bpf: fix clearing buffered output between tests/subtests
Patch-mainline: v5.4-rc1
Git-commit: bf8ff0f8cfd73e850c01b453ddb79609bd83279c
References: bsc#1154353

Clear buffered output once test or subtests finishes even if test was
successful. Not doing this leads to accumulation of output from previous
tests and on first failed tests lots of irrelevant output will be
dumped, greatly confusing things.

v1->v2: fix Fixes tag, add more context to patch

Fixes: 3a516a0a3a7b ("selftests/bpf: add sub-tests support for test_progs")
