meta-phosphor: change systemd.bbclass to match upstream override syntax
Upstream bbclasses changed to typically use the `:${PN}` override
syntax, including the SYSTEMD_ variables. Change our systemd.bbclass
to do the same for consistency and perform a tree-wide variable
replacement.
Spot checked by building bletchley and witherspoon and checking
some of the SYSTEMD_LINK directives on installed packages under qemu.
