Thanks!

Pushed as 4a829b2d55bc9b0ad5a335c8228a7d2371fa1d9a with the following
changes...

I corrected the commit message (changing "datastructures.scm" to
"digest.scm"), tweaked the logic of the builder to be more idiomatic,
and removed the period at the end of the synopsis (`guix lint`
complained).

Regarding the builder:

1) install-file does mkdir-p [0], so that can be omitted.
2) I think it's more clear to use "include" rather than "src" when
binding the output's include directory
3) Using with-directory-excursion instead of chdir is more in tune with
a functional coding style [1], in my opinion
