tools: bpftool: add bash completion for bpftool Add a completion file for bash. The completion function runs bpftool when needed, making it smart enough to help users complete ids or tags for eBPF programs and maps currently on the system. Update Makefile to install completion file to /usr/share/bash-completion/completions when running `make install`. Emacs file mode and (at the end) Vim modeline have been added, to keep the style in use for most existing bash completion files. In this, it differs from tools/perf/perf-completion.sh, which seems to be the only other completion file among the kernel sources repository. This is also valid for indent style: 4-space indents, as in other completion files.
