libbpf: Fix single-line struct definition output in btf_dump
[ Upstream commit 872aec4b5f635d94111d48ec3c57fbe078d64e7d ]
btf_dump APIs emit unnecessary tabs when emitting struct/union
definition that fits on the single line. Before this patch we'd get:
struct blah {<tab>};
This patch fixes this and makes sure that we get more natural:
struct blah {};
Fixes: 44a726c3f23c ("bpftool: Print newline before '}' for struct with padding only fields")
