[bug#45600] [PATCH] /etc/profile.d/guix.sh: Add guix pull profile even when absent

[Jakub Kądziołka]

After initial installation on a foreign distro, the guix pull profile
won't be present in path. This means that the first guix pull won't take
effect until the shell is restarted.

~/.guix-profile cannot be pre-loaded like this as the relevant paths are
stored in ~/.guix-profile/etc/profile, which simply won't exist.
However, guix package will output a relevant hint that instructs the
user to reload the profile, so this isn't a problem.
---

Note on testing: I have verified that non-existent directories are
harmless when included in $PATH and $INFOPATH. However, fully testing
this change requires setting up a virtual machine and installing Guix on
it, which I cannot do right now.

LGTM!

Please add something like this to the commit log:

* etc/guix-install.sh (sys_create_init_profile): Set PATH and INFOPATH
even when $_GUIX_PROFILE does not exist.

Thank you,
Ludo’.
