meson: kill meson.build as it's not used anymore

Browse Source 
Meson.build was added to facilitate systemd integration, but systemd
integration went different direction and we don't need meson.build
anymore. So remove it and not maintain it anymore.

To integrate libbpf into a project which uses Meson building system define
`[wrap-git]` file in `subprojects` folder.
To add libbpf dependency to the parent parent project, e.g. for
libbpf_static_dep:
```
libbpf_obj = subproject('libbpf', required : true)
libbpf_static_dep = libbpf_proj.get_variable('libbpf_static_dep')
```
To validate changes to meson.build
```bash
$ python3 meson.py build
$ ninja -C build/
```
To install headers, libs and pkgconfig
```bash
$ cd build
$ ninja install
```
