SERIAL_CONSOLES improvements

Having two variables to enable essentially the same behaviour isn't really desirable, so fix up the handling of SERIAL_CONSOLES, set it from SERIAL_CONSOLE by default if not set and change everwhere we read SERIAL_CONSOLE to read from SERIAL_CONSOLES instead. This should allow us to deprecate SERIAL_CONSOLE whilst retaining compatibility with machine configurations that still use it.

Note: I'm a bit concerned about the default setting of SERIAL_CONSOLE in systemd-serialgetty; I'm not sure why this is needed given that this is almost always going to be machine-specific. I've left it alone for the time being however.

The following changes since commit e86538db13605953465aacc3f2fb7d719dad919e:
