Subject: [PATCH] man: mention that sd_id128_get_boot() and friend may return
-ENOSYS
And drop to mention sd_id128_get_boot_app_specific() may return -ENOENT
or -ENOMEDIUM. The function does not read /etc/machine-id. But reads a
file in the procfs, which is a kind of the kernel API. Hence the
failures are caused only when the system has wrong setup.
(cherry picked from commit c576920e673114529c5bfe5ea29891a24a443338)
