* path.cc (path_conv::check): Set case_clash even if pcheck_case

Browse Source 
is set to PCHECK_ADJUST when a case clash is given for the last
        component in path.
        (symlink_info::case_check): Ditto.
        * syscalls.cc (_rename): Avoid overwriting an already existing file
        if a case clash is given even if pcheck_case is set to PCHECK_ADJUST.
