This adds a simple condition/assert/match to the service manager, to udev's .link handling and to networkd, for matching the kernel version string. In this version we only do fnmatch() based globbing, but we might want to extend that to version comparisons later on, if we like, by slightly extending the syntax with ">=", "<=", ">", "<" and "==" expressions.
