core: use the generic module_load() function

Browse Source 
This allows aliases to be used for the basic modules we load from pid1 before
udev is started. In #9501 the kernel renamed autofs4 to autofs, with "autofs4"
as alias, but we wouldn't load the module, because we didn't follow aliases.
The kernel change was reverted, but it's probably better to support aliases.
