systemd: resolved linked even if the option is disabled

in the do_install function in systemd recipe the condition to check
if the resolved option is selected is reversed (wrong !).
This is for example true if we compile systemd with musl instead of
glibc (every poky-image-minimal recipe).

Also no link should be created if the option is not selected
nor an ALTERNATIVE set.
