Update after gnulib changed.

* autogen.sh: When invoking gnulib-tool for libgrep, don't pass the option
--avoid=mbszero. Since 2026-05-06, gnulib module 'regex' depends on gnulib
module 'localeinfo', which depends on gnulib module 'mbszero', and this
produced a build failure on MSVC: "unresolved external symbol mbszero".
