glib-aux: add nmtst_assert_cmpmem() helper
g_assert_cmpmem() exists, but it does not print the actual buffer
content on test failure. It is useful to see what actually failed in
the test output.
Also, nmtst_assert_cmpmem() prints a backslash escaped output, that you
can unescape in the terminal with `echo -e`. You can also directly copy
and paste the output to C source code.
