Subject: [PATCH] tools/libxenstat: ensure strnlen() declaration is visible

Its guard was updated such that it is visible by default when POSIX 2008
was adopted by glibc. It's not visible by default on older glibc.

Fixes: 40fe714ca424 ("tools/libs/stat: use memcpy instead of strncpy in getBridge")
