core: raise the log priority if sd-executor is missing

Browse source 
Log about missing executor at the emergency level, so the message always
makes it to the console - otherwise it won't get anywhere, since we
can't even start systemd-journald in that case.

Before:

Welcome to Arch Linux!

[!!!!!!] Failed to allocate manager object.
[    5.207741] systemd[1]: Freezing execution.

After:
