[elpa] elpa-admin f0b1b51fc7: Add support for GNU Guix

[Philip Kaludercic]

branch: elpa-admin
commit f0b1b51fc76625e852f3f21945d4dc32ea9845ea
Author: Philip Kaludercic <philipk@posteo.net>
Commit: Philip Kaludercic <philipk@posteo.net>

    Add support for GNU Guix
    
    * elpa-admin.el (elpaa--sandbox-ro-binds): Add /gnu to the list of
    read-only directories so that a "Guix" Emacs can access its site-lisp
    files.
    * elpa-manifest.scm: Add a Guix manifest file with all the necessary
    packages to use GNU ELPA.
    
    The manifest file is added to the admin branch, so that if
    elpa-admin.el requires a new dependency, the change can be made
    centrally and will be reflected in both elpa.git and nongnu.git.
    
    elpa-manifest.scm is symbolically linked into the repositories'
    respective root directories at initialisation, as is already the case
    with the GNUmakefile.  By linking it, the file will be renamed to the
    more conventional "manifest.scm".  We use "elpa-manifest.scm" here to
    avoid confusing a "guix shell" invocation, that is hard-coded to check
    for a "manifest.scm" and "guix.scm" file.
