do not remove bits/uClibc_ctype.h when !UCLIBC_HAS_CTYPE_TABLES

When building without locale support (i.e. only a stub) it is desireable
to be able to disable the table based ctypes and use the header only
implementation, but this file is deleted when UCLIBC_HAS_LOCALE is not on.

Fixes: b4a3345ea ("remove uClibc_ctype.h if !LOCALE")
