bug#47584: [PATCH 2/3] WIP gnu: Change the Guile used for activation to one that has 'openat'.

[Maxime Devos]

TODO: when doing "make check-system TESTS=ldap", I get a build failure
of openssl@1.1.1l, I suspect it's a situation like
<https://issues.guix.gnu.org/56137> again, though I haven't investigated yet.

This is required by the next patch, in which 'mkdir-p/perms'
uses 'openat'.

* gnu/packages/guile.scm (guile-for-activation): New variable.
* gnu/services.scm (activation-script)[actions]: Set #:guile to
guile-for-activation.
* gnu/packages/make-bootstrap.scm (%guile-static-stripped/initrd):
New variable.
* gnu/system/linux-initrd.scm (expression->initrd): Use
%guile-static-stripped/initrd instead of %guile-static-stripped.
