dev-libs/libxslt: Fix glibc-2.26 compatibility. Patch by Quentin Minster.

This patch is much less intrusive than the upstream solution, so using
it for now. Revision bump since the current version unconditionally includes
in public headers xlocale.h ...

Closes: https://bugs.gentoo.org/632214
Package-Manager: Portage-2.3.13, Repoman-2.3.4
