[PATCH AUTOSEL 6.6 003/104] selftests/bpf: fix RELEASE=1 build for tc_opts

[Sasha Levin]

From: Andrii Nakryiko <andrii@xxxxxxxxxx>

[ Upstream commit 2b62aa59d02ed281fa4fc218df3ca91b773e1e62 ]

Compiler complains about malloc(). We also don't need to dynamically
allocate anything, so make the life easier by using statically sized
buffer.
