bug#57136: Snakemake cannot execute remote jobs

[Konrad Hinsen]

The execution of Snakemake workflows fails on a cluster because the
script that Snakemake executes remotely does not reference Python
correctly.

This is due to a patch applied in the Guix package
definition (build phase call-wrapper-not-wrapped-snakemake, 
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/python-xyz.scm#n9713)
which is outdated. The corresponding code in Snakemake was changed
significantly in the following commit:

Cheers,
