Hi!

We've got quite a few packages that simply copy some files from their
source to the output.  Examples include `debian-archive-keyring`,
`0ad-data`, `gcide`, or `rofi-pass`.

Those packages end up being tedious to write because we need to rely on
the trivial-build-system, also known as "the least trivial of them all!" :)

What about adding a "copy-build-system" which has one argument, say an
`#:install-plan` that takes a list of source-destination pairs?

This would drastically simplify the definition of the aforementioned
packages, basically summing up dozens of boilerplate lines into an
effectively trivial file mapping.

If this sounds like a good idea, I'd be happy to send a patch!

Cheers!
