blkid: recognize ext3 with test_fs set as ext3

It seems that if we have the test_filesystem flag set on an ext3
filesystem(!) on a system which provides ext4, blkid gets confused.

According to the current logic:

* It's not an ext4dev filesystem, because the system provides ext4.
* It's not an ext4 filesystem, because it has no ext4 features.
* It's not an ext3 filesystem, because the test flag is set.

In the end, it's nothing.

blkid should return *something* that is mountable... I'm inclined to
think that ext3 should be the right answer, if no ext4-specific features
are set.

This would mean just dropping the EXT2_FLAGS_TEST_FILESYS test in
probe_ext3(), because ext4 & ext4dev probes have come first already.

blkis: fix detection of ext4dev as ext4

If only ext4 is available (as a module or in /proc/filesystems)
blkid wasn't properly testing for it, because the time checks
were backwards and always failed.  This caused old ext4dev
filesystems to fail to mount as ext4.  With this patch it works
fine.

Also, don't try to check for modules on a non-Linux system.

blkid: Optimize devicemapper support

This commit works by removing all calls from libdevmapper altogether,
and using the standard support for "normal" non-dm devices.

It depends on dm devices being placed in /dev/mapper (but the previous
code had this dependency anyway), and /proc/partitions containing dm
devices.

We don't actually rip out the libdevmapper code in this commit, but
just disable it via #undef HAVE_DEVMAPPER, just so it's easier to
review and understand the fundamental code changes.  A subsequent
commit will remove the libdevmapper code, as well as unexport
the blkid_devdirs string array.

Thanks to Karel Zak for inspiring me to look at the dm code in blkid,
so I could realize how much it deserved to ripped out by its roots.  :-)

The classic way is to return the first successfully detected signature
(filesystem/raid).  Unfortunately, sometimes we need to check for all
possible signatures, because on some volumes (e.g. CD-ROMs) is possible
to store multiple filesystems.

Sometimes we need to check for all filesystems to avoid situation that
we return wrong result (e.g. swap and FAT on the same device).
