tools/gnulib: update to branch stable-202501

Move to the June 2025 update of the first 2025 stable branch
in order to better support updating gettext to the latest versions.

More instances of blocking the defining of functions
that use reallocarray() is needed for portability with macOS
as more similar functions have been added.
And one instance is removed as the function was removed.
Refer to a previous commit to explain the need for this.

Manually adjusted patch:
 - 150-portable-tdestroy.patch
 - 160-flag-reallocarray.patch
 - 200-force-disable-after-configure.patch

Removed upstreamed patch:
 - 500-acl-function-name.patch

All other patches are automatically refreshed.
