Subject: posix-shell: utils: Add automeson()

This function allows to run `meson compile -C <build-dir>` always for a
given build directory whenever an also given file is written.

This is especially useful to edit LaTeX files and let them update
automatically on each save of the editor with automeson, meson and
latexmk.

The performance is so good that it speeds up the LaTeX and especially
TikZ development significantly.
