[bug#54581] Add emacs-sqlite3-api package

[Roman Scherer]

Hi Maxime,

here's a new patch as per your suggestion. I'm removing the code that
downloads from the internet, and the call to date for the NOW variable.

I also remove the SQLITE_STATIC and SQLITE_TRANSIENT sections in the
generated constants.c file, they cause a warning and would have been
remove by the original script.

I changed the #:tests? keyword to (%current-target-system), but I
noticed the tests of the package are now not run anymore when I build
the package. Is this expected?

I tried to specify a target when building the package, but this gives me
the following error:

./pre-inst-env guix build emacs-sqlite3-api --target=x86_64
guix build: error: 
/home/roman/workspace/guix/gnu/packages/emacs-xyz.scm:5738:4: 
emacs-sqlite3-api@0.15-0.7cb4b66: build system `emacs' does not support cross 
builds

Do you know how I can trigger the tests when building this package from
the command line, or even better from within Emacs?

Well, I was looking at the last time the consts.c has been modified by
the maintainer and it was 2 years ago.

I was thinking it would be more stable to use the code that ships with
the repository, rather than building something from the internet which
hasn't been updated for 2 years.

But if this file is considered object code, ok.
