meson: define the various files litest needs to copy rules/hwdb in place

This was motivated by the need to run the test runner from any directory, so
we need absolute paths to the files we copy.

Unfortunately, we can't get the absolute path from the object returned by
configure_file() and we can't feed that directly into join_paths() either.
So let' make it at least easier to handle: create a configure_file for all the
files we need (so they all end up in builddir/) and simply hardcode the name
for join_paths. Define the lot in config.h, no need to pass compiler flags
around.
