Compile the contents of a few essential target unit files (graphical.target, multi-user.target, rescue.target, etc.) into the manager binary, with comments stripped, and fall back to those built-in copies when no fragment is found on disk. This lets the manager reach a usable state even on a system that ships none of these unit files, e.g. in minimal environments or one-off chroots. On-disk files always take precedence (masks included), as the fallback is only consulted when nothing is found in the lookup paths. The unit file list is defined in units/meson.build and embedded via a small generator script; 'units' is now processed before 'src/core' so the list is available there. The set of units and services is selected that should allow for a normal operation of starting/stopping/restarting, of the machine. The services all use SuccessAction=…, so they don't require any binaries to be installed. sigpwr.target is included, even though it doesn't do anything useful. The same is true in normal installations. We might want to change it do something useful there too.
