core/pkg-utils: add macro to escape-and-printf
In some cases we need to escape make variables and pass them to
printf(1).
This is the case in our fs infra, where we want to shoe-horn the
commands to generate the filesystems in the fakeroot script, or the
devices, permissions and users tables to their respective files.
We currently do so by replacing $(sep) with the literal '\n' but that's
not enough. This does not protect against strings with an embedded '%'
or a backslash.
Add a new macro that properly escapes a string and calls printf(1), so
that we get the expected output.
