systemd: fix libnss-mymachines packaging

By removing libnss_mymachines.so.2 from FILES:${PN}-container it
correctly gets packaged into libnss-mymachines, just like the other
libnss-* components, due to PACKAGES_DYNAMIC.

To make up for the missing lib in the container package, I added
libnss-mymachines to RDEPENDS:${PN}-container. As I understand it,
the lib should be installed even without this if anything from the
container package links against it. But since I don't know if there
was a special reason to explicitly add it to the container files list,
like something using dlopen to load the lib, it seemd to be the
safest option.

musl based targets do not build libnss-mymachines so please make this
dependency only for glibc
