Subject: [PATCH] tools/tests: allow depriv-fd-checker to build with really old
 Linux headers

Assuming it was intentional for this test utility, other than most other
ones, to always be built, I think it would be nice if it didn't fail to
build on really old distros just because of the lack of a TUNGETIFF
definition.
