Cleaning up the /bin for guix.

[Roel Janssen]

Dear Guix,

When installing ‘guix’ in a profile, the ‘bin’ directory of that profile
contains:

asn1Coding -> 
/gnu/store/2fg01r58vv9w41kw6drl1wnvqg7rkv9d-libtasn1-4.12/bin/asn1Coding

I suspect that the Scheme files don't belong in ‘bin’.  What about the
others?  Can we do better here than propagate ‘gnutls’ and ‘nettle’?

Kind regards,
Roel Janssen
