systemd: Sync systemd-serialgetty@.service with upstream

This is now causing runtime problem for qemuarm64. The default.target
is not reached until a timeout. Output is like below.

Bootup is not yet finished (org.freedesktop.systemd1.Manager.FinishTimestampMonotonic=0).
Please try again later.

We can see that we are waiting for /dev/hvc0, while in fact there's no /dev/hvc0.
Jason's commit actually solves such problem.
So restore to use Jason's method. Do not use 'BindsTo'.
