[PATCH 2/4] testsuite: add function declarations for __xstat family

[Emil Velikov <emil.l.velikov@gmail.com>]

From: Emil Velikov <emil.velikov@collabora.com>

As the inline comment says - the declarations have been dropped with
glibc 2.32.9000, as a result the build throws a set of lovely warnings.

Inspired by umockdev, which bears the same license as this project.
