[bug#43367] [PATCH 1/5] utils: wrap-program: Refuse to wrap .X-real files.

[Brendan Tildesley <mail@brendan.scot>]

*    guix/build/utils.scm: (wrap-program): Error if wrap-program was
mistakenly passed a .X-real file. This prevents and forces us to fix
cases where a double wrapped ..X-real-real file is created, such as can
be seen with:

find /gnu/ -iname '.*-real-real'
