Kirill, ports,

While searching for where getexecpath can/should be used, I found this
here in libggml. This diff should replicate what is done on other
platforms by their idiosyncratic methods (_NSGetExecutablePath,
procfs). It builds, but I don't really know how to use this library.
Could maybe use a test run.
