system: operating-system-etc-service: Unset GUIX_PROFILE.
This seems to have been omitted, currently users on default Guix System
installations do have GUIX_PROFILE set to their ~/.config/guix/current.
This is wrong and can lead to some surprises when sourcing etc/profile
of a Guix profile.
Followup of 50a2d73eac1577e35b526d3fc91423b97e581aef.
* gnu/system.scm (operating-system-etc-services): Clean up GUIX_PROFILE.
