exec_cmd: RUNTIME_PREFIX on z/OS systems
Enable Git to resolve its own binary location using __getprogramdir
and getprogname.
Since /proc is not a mandatory filesystem on z/OS, we cannot rely on the
git_get_exec_path_procfs method to determine Git's executable path. To
address this, we have implemented git_get_exec_path_zos, which resolves
the executable path by extracting it from the current program's
directory and filename.
