Subject: Fix `find_program` function to be less fragile

Look for executable path using system utility `which` instead of fragile regular expressions. See $447 for details. Also see discussion in [neovim](https://github.com/neovim/neovim/issues/3620#issuecomment-154757577) issues.

Subject: Use `command -v` for obtaining executable path.

Seems like `command -v` is defined by POSIX and therefore should be compatible with all POSIX OSes.
