[PATCH] bpftool: exclude bash-completion/bpftool from .gitignore pattern

[Masahiro Yamada]

tools/bpf/bpftool/.gitignore has the "bpftool" pattern, which is
intended to ignore the following build artifact:

  tools/bpf/bpftool/bpftool

However, the .gitignore entry is effective not only for the current
directory, but also for any sub-directories.

So, the following file is also considered to be ignored:

  tools/bpf/bpftool/bash-completion/bpftool

It is obviously version-controlled, so should be excluded from the
.gitignore pattern.

You can fix it by prefixing the pattern with '/', which means it is
only effective in the current directory.

I prefixed the other patterns consistently. IMHO, '/' prefixing is
safer when you intend to ignore specific files.
