We already return an error code unconditionally when building with
!CONFIG_GLOB. We need to do the same for globfree. Otherwise,
we run risk of corrupting memory.
This issue exists since the code was first added, but it became
more acute with 90cde3b9ff46 ("startup: Execute init scripts in
alphabetical order"), which added a globfree into the shell init.
Configuration without CONFIG_GLOB would from then on experience
memory corruption during startup.

opendir() can trigger automounts, so do not use it when the
pattern we examine doesn't have any wildcards.

The arguments to collated_compare are actually pointers to
pointers to char, not pointers to char.

This allows us for example to execute init scripts in the correct
order.
