    libc/include/wchar.h: Remove parameter name
    
    As discussed in GCC bug 97088
    (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97088), parameters in
    prototypes of library functions should use reserved names, or no name
    at all.
    
    This patch removes the 'ptr' parameter name from
    wint_t _getwchar_r (struct _reent *);
    wint_t _getwchar_unlocked_r (struct _reent *);
    
    to avoid possible clashes with user code in case someone uses
    before including Newlib's wchar.h (or uses some other conflicting
    definition)
