test: correctly mask supporting services in tests, take #2

Due to a little misunderstanding the last patch doesn't work as
expected, since test_create_image() is called only for the first image
(usually TEST-01-BASIC), and all subsequent images are then (possibly)
modified with test_append_files().

Follow-up to 179ca4d2b1b5579014773a128462475f99b7a91b.

-         *    a nicely read-only fd in the reading side. However, they are by default quite small, and unprivileged
-         *    clients can only bump their size to a system-wide limit, which might be quite low.
-         *
-         * c) Then, we try an O_TMPFILE file in /dev/shm (that dir is the only suitable one known to exist from
-         *    earliest boot on). To make it read-only we open the fd a second time with O_RDONLY via
-         *    /proc/self/<fd>. Unfortunately O_TMPFILE is not available on older kernels on tmpfs.
-         *
-         * d) Finally, we try creating a regular file in /dev/shm, which we then delete.

+         * a) First we try to use memfds. They are the best option, as we can seal them nicely to make them
+         *    read-only. Unfortunately they require kernel 3.17, and – at the time of writing – we still support 3.14.
+         *
+         * b) Then, we try classic pipes. They are the second best options, as we can close the writing side, retaining
+         *    a nicely read-only fd in the reading side. However, they are by default quite small, and unprivileged
+         *    clients can only bump their size to a system-wide limit, which might be quite low.
+         *
+         * c) Then, we try an O_TMPFILE file in /dev/shm (that dir is the only suitable one known to exist from
+         *    earliest boot on). To make it read-only we open the fd a second time with O_RDONLY via
+         *    /proc/self/<fd>. Unfortunately O_TMPFILE is not available on older kernels on tmpfs.
+         *
+         * d) Finally, we try creating a regular file in /dev/shm, which we then delete.
