env.c: Try create base directory on every call to env_get_dir()

Browse source 
Not a huge performance loss anyway. And the directory may be deleted
between calls so. However the directory can still be missing as soon
as the mkdir() call has ended.

Doing it this way just means that if the directory is removed during
execution of the program, it will be created again and not make the
rest of the programs lifetime live without it.
