exec_cmd: RUNTIME_PREFIX on some POSIX systems
Enable Git to resolve its own binary location using a variety of
OS-specific and generic methods, including:
- procfs via "/proc/self/exe" (Linux)
- _NSGetExecutablePath (Darwin)
- KERN_PROC_PATHNAME sysctl on BSDs.
- argv0, if absolute (all, including Windows).
This is used to enable RUNTIME_PREFIX support for non-Windows systems,
notably Linux and Darwin. When configured with RUNTIME_PREFIX, Git will
do a best-effort resolution of its executable path and automatically use
this as its "exec_path" for relative helper and data lookups, unless
explicitly overridden.
Small incidental formatting cleanup of "exec_cmd.c".
