meson: use a convenience static library for nspawn core

This makes it easier to link the nspawn implementation to the tests.
Right now this just means that nspawn-patch-uid.c is not compiled
twice, which is nice, but results in test-patch-uid being slightly bigger,
which is not nice. But in general, we should use convenience libs to
compile everything just once, as far as possible. Otherwise, once we
start compiling a few files here twice, and a few file there thrice, we
soon end up in a state where we are doing hundreds of extra compilations.
So let's do the "right" thing, even if is might not be more efficient.
