Steve Haslam 2a7e0eeb48 Glean libexec path from argv[0] for git-upload-pack and git-receive-pack. ...

If the user specified the full path to git-upload-pack as the -u option to
"git clone" when cloning a remote repository, and git was not on the default
PATH on the remote machine, git-upload-pack was failing to exec
git-pack-objects.

By making the argv[0] path (if any) available to setup_path(), this will
allow finding the "git" executable in the same directory as
"git-upload-pack". The default built in to exec_cmd.c is to look for "git"
in the ".../libexec/git-core" directory, but it is not installed there (any
longer).

Much the same applies to invoking git-receive-pack from a non-PATH location
using the "--exec" argument to "git push".
