[PATCH] libkmod: Always search modules.builtin if no alias has been found

[Peter Kjellerstedt <pkj@axis.com>]

Commit 89443220e broke the lookup for builtin modules. modules.builtin
was no longer searched if kmod_lookup_alias_from_kernel_builtin_file()
returned 0.

I do not know if this is the correct thing to do, or if the commit
message makes any sense. However, it solves the problem we were seeing.
We use fuse, which installs /etc/modules-load.d/fuse.conf to load the
fuse kernel module. However, we have fuse built-in. Normally, the
following can be seen in the log:

  systemd-modules-load[192]: Module 'fuse' is built in

but after commit 89443220e, we instead got:

  systemd-modules-load[193]: Failed to find module 'fuse'
