[PATCH 10/12] tools lib bpf: Change FEATURE-DUMP to FEATURE-DUMP.libbpf

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Yunlong Song <yunlong.song@huawei.com>

Commit ed63f34c026e9a60d17fa750ecdfe3f600d49393 ("perf tools: Make perf
depend on libbpf") triggers the build of libbpf when building the perf
tools, dynamically creating FEATURE-DUMP.libbpf.

It failed to update the tools/lib/bpf/.gitignore file to have that
prefix, fix it.
