Check the arguments passed to ./configure.

For now, don't allow arguments, since ./configure doesn't actually
support any.  Previously "./configure --help" would print misleading
information, and any other arguments were silently ignored.

Note linux-libc-dev build dependency (for ext2_fs.h).

Signed-off-by: Rob Browning <rlb@defaultvalue.org>
Remove dependency on linux/ext2_fs.h

Due to a missing header in (some versions of) linux/ext2_fs.h,
configure's AC_CHECK_HEADERS test fails for this header, making it
appear "not found", and causing Linux-attr support to be disabled in bup
for no good reason.

Given that all the flags bup needs are available in linux/fs.h, we can
safely remove the requirement for linux/ext2_fs.h altogether, to work
around the problem.

Explicitly select the "du" block size in t/test.sh.

Since du's default output can be affected by several environment
variables (DU_BLOCK_SIZE, BLOCK_SIZE and BLOCKSIZE), be explicit about
what we want via -B 1024.

Explicitly use "du -k" to set block size in t/test.sh.

Commit e3514812 (Explicitly select the "du" block size in t/test.sh)
used the parameter "-B 1024" which isn't portable. Now use "du -k"
to explicitly get output in kilobytes.

At least du(1) on Linux (GNU coreutils), Mac OS X, FreeBSD, NetBSD,
and OpenBSD support this option.

Remove the "if pst:" guard in index-cmd.py, since it doesn't appear to
