[PATCH 02/11] test-cutils: Use g_assert_cmpuint where appropriate

[Eric Blake <eblake@redhat.com>]

When debugging test failures, seeing unsigned values as large positive
values rather than negative values matters (assuming that the bug in
glib 2.76 [1] where g_assert_cmpuint displays signed instead of
unsigned values will eventually be fixed).  No impact when the test is
passing, but using a consistent style will matter more in upcoming
test additions.  Also, some tests are better with cmphex.

While at it, fix some spacing and minor typing issues spotted nearby.
