Sahid Orentino Ferdjaoui 9b81075534 bpftool: remove support of --legacy option for bpftool
Following:
  commit bd054102a8 ("libbpf: enforce strict libbpf 1.0 behaviors")
  commit 93b8952d22 ("libbpf: deprecate legacy BPF map definitions")

The --legacy option is no longer relevant as libbpf no longer supports
it. libbpf_set_strict_mode() is a no-op operation.

-h, --help
Print short help message (similar to **bpftool help**).
-V, --version
Print bpftool's version number (similar to **bpftool version**), the
number of the libbpf version in use, and optional features that were
included when bpftool was compiled. Optional features include linking
against LLVM or libbfd to provide the disassembler for JIT-ted
programs (**bpftool prog dump jited**) and usage of BPF skeletons
(some features like **bpftool prog profile** or showing pids
associated to BPF objects may rely on it).
-j, --json
Generate JSON output. For commands that cannot produce JSON, this
option has no effect.
-p, --pretty
Generate human-readable JSON output. Implies **-j**.
-d, --debug
Print all logs available, even debug-level information. This includes
logs from libbpf as well as from the verifier, when attempting to
load programs.
