[bug#33308] [PATCH 1/2] gnu: mash: Update to 2.1.

[Christopher Baines <mail@cbaines.net>]

I'm looking to upgrade capnproto, and mash fails to build with 0.7. Therefore,
update it, and tweak the compilation to allow it to build with 0.7. The
package also builds with the current version of capnproto. I got the idea of
changing the c++ version from here [1].

1: https://github.com/marbl/Mash/issues/98

* gnu/packages/bioinformatics.scm (mash)[version]: Change to 2.1.
[source]: Update sha256 hash.
[arguments]: Add new use-c++14 phase, to patch source to build using c++14.
