Recent glibc deprecated/dropped the `__xstat*()` family from the header
files, so the build started to fail on "no previous prototype". However,
umockdev still needs needs to keep the wrappers to run programs that got
built against an earlier glibc.

Thus declare the prototype explicitly. It should still fail to build if
glibc defines it differently.

Fixes #108
