bug#67240: dev: “make” of Guix fails, non-existent .git/hooks directory

Hi,

On a very fresh install of a system, I have just cloned the Guix
repository then run the dance ./bootstrap, ./configure and make.  It
fails because:

--8<---------------cut here---------------start------------->8---
cp: cannot create regular file '.git/hooks/pre-push': No such file or directory
make[2]: *** [Makefile:7454: .git/hooks/pre-push] Error 1
make[2]: Leaving directory '/home/simon/src/guix/guix'
make[1]: *** [Makefile:6137: all-recursive] Error 1
make[1]: Leaving directory '/home/simon/src/guix/guix'
make: *** [Makefile:4253: all] Error 2
--8<---------------cut here---------------end--------------->8---

In the file Makefile.am, nothing check that the directory .git/hooks
exists before copying to it.  By default, it does not seem created.  At
least, it was not with a fresh clone using Git from Guix revision
fc6bdaa.

I propose this patch attached.
