Use the 'extern-inline' module explicitly where needed

[Bruno Haible]

When a .h file uses _GL_INLINE_HEADER_BEGIN / _GL_INLINE_HEADER_END,
it needs a dependency towards the 'extern-inline' module.

Some modules had this dependency only accidentally; it's better to
have it explicitly, for maintenance.

I found the list of affected modules through
$ for m in $(for f in `fgrep -l _GL_INLINE_HEADER_BEGIN lib/*.h | sort`; do 
./gnulib-tool --find $f; done); do
    if grep '^extern-inline' modules/$m > /dev/null; then :; else echo $m; fi;
  done
