The previous commit pointed out an unfortunate problem with the

ap_os_case_canonical_filename() interface: It returns const char * on
platforms where no mapping is ever performed but char * on platforms
where mapping can occur.  Such a discrepancy seems to be a good choice,
as no platform is penalized with extra pathlength.

This tweak gets rid of a const misuse warning on systems where
ap_os_case_canonical_filename() returns const char *.
