CurrentSymlink= accepts a symlink path, but the parser used NAME_MAX
for specifier expansion. Absolute and target-relative paths can be
longer than one filename component while still staying below PATH_MAX.
Reproducer: configure CurrentSymlink= to a path longer than NAME_MAX
and run systemd-sysupdate list with debug logging.
Before: sysupdate logged that CurrentSymlink= specifier expansion
failed and ignored the setting.
After: the transfer parses cleanly and list emits no CurrentSymlink=
specifier expansion warning.
