ftello: Provide a non-inline replacement of ftell().

* lib/stdio.in.h (ftell): Don't provide if module 'ftell' is not used.
* m4/ftell.m4 (gl_FUNC_FTELL): Replace ftell also if the system does
not have ftello() (such as on mingw).
* modules/ftello (Depends-on): Add ftell.
* modules/ftell (License): Change to LGPLv2+.
