Dear maintainer,

keyutils fails to build from source when built inside a container:

The "unary operator expected" issue is because maxsquota is undefined.
Indeed it is defined by looking at /proc/key-users for user 0 (root),
however this user does necessary not exists in a container. In addition
as the testsuite is run as non-root (contrary to what upstream
recommends), I believe the returned values are incorrect. At least on my
system they are quite different between root and normal users.

This simple one-liner fixes the issue, and should still work fine with
the testsuite run as root:
