modules: generate plain module names via version filters

modules: generate plain module names via version filters

Replace conditional "LINUX_6_12:mod" / "!LINUX_6_12:mod" AUTOLOAD entries
with version-filtered module names using @lt6.18 / @ge6.18. This makes
version_filter emit plain module names into /etc/modules.d(e.g. "crc32c_generic"),
allowing kmodloader to find and load the correct module for the running kernel.
Fixes crc32c (and related crypto modules) not being autoloaded on 6.12 kernels.
