sysupdate: allow long metadata URLs

Browse Source 
138829b784 moved Documentation=, AppStream=, and related URL parsing
into sysupdate-config.c, but kept NAME_MAX as the specifier expansion
limit. These settings are URLs, not filenames.

Reproducer: configure a feature Documentation= URL longer than
NAME_MAX and run systemd-sysupdate features FEATURE.

Before: the URL was ignored after ENAMETOOLONG during specifier
expansion.

After: features FEATURE prints the long Documentation URL.
