This causes a warning in the unit test:

../../gltests/test-readutmp.c:45:29: warning: pointer targets in passing 
argument 2 of ‘read_utmp’ differ in signedness [-Wpointer-sign]

This patch fixes it.

        readutmp tests: Fix gcc warning (regression from yesterday).
        * tests/test-readutmp.c: Include idx.h.
        (main): Use idx_t instead of size_t.
