ylwrap: rename header inclusion in generated parsers

Some types of Bison parsers, such as the GLR ones, generate a header
file that they include.  ylwrap, which renames the generated files,
does not rename the included file.  Fix this shortcoming, reported
for instance here:
<http://lists.gnu.org/archive/html/bug-bison/2012-06/msg00033.html>.
Fixes t/yacc-bison-skeleton.sh, see Automake bug#7648 and PR automake/491.

* lib/ylwrap (quote_for_sed): Accept arguments.
Catch more special characters.
(rename_sed): New.
Improve the previous renaming sed commands using quote_for_sed.
Suggested by Stefano Lattarini here:
<http://lists.gnu.org/archive/html/automake-patches/2012-07/msg00095.html>.
(main loop): Use rename_sed to rename the dependencies to other files.
* t/yacc-d-basic.sh: Exercise this case, even if bison/yacc was
not issuing such an include.
* t/list-of-tests.mk (XFAIL_TESTS): Adjust.
