On 32 bit systems, _FILE_OFFSET_BITS will be set to 64 by
AC_SYS_LARGEFILE. This causes the glibc headers to use readdir64 rather
than readdir. Emulate that behavior in the preloader or the tests will
all fail with "No such file or directory".
Having undefined (but in practice rarely changing) ordering for
`readdir()` ended up screwing us over for bootloader config
generation; see https://bugzilla.redhat.com/show_bug.cgi?id=1226520
Let's make things significantly more likely to fail more quickly in
the future if similar bugs are introduced. We accomplish this by
introducing a little `LD_PRELOAD` library that randomizes the results
of `readdir()`.
