Zbigniew Jędrzejewski-Szmek 83b6af36d1 meson: add test-dlopen
test-dlopen is a very simple binary that is only linked with libc and
libdl. From it we do dlopen() on the nss and pam modules to check that they are
linked to all necessary libs.

(meson-compiled nss modules are linked to less libraries, for whatever reason.
I suspected that some deps are missing, but it turns out that my suspicions
weren't justified, and the modules load just fine. Let's keep the test though,
it is very quick, and might detect missing linkage in the future.)
