util: move SCCreateDirectoryTree to util-path

Renames SCLogCreateDirectoryTree to SCCreateDirectoryTree
and move into a util module for re-use.

Also moves SCMkDir from suricata-common.h to the more
appropriately names util-path.h.

I would have prefered to use util-file for file related options
but that is already used by file store utilities. util-path
is close enough for file related operations.
