Added a simple ls to a nonexistent directory for test 1.
In case the driver is broken for a nonexistent directory, U-boot
might crash.

Here is an example failed output:

=> # Test Case 1 - ls
=> ext4ls host 0:0
<DIR>       4096 .
<DIR>       4096 ..

      2621440000 2.5GB.file
         1048576 1MB.file
=> # In addition, test with a nonexistent directory to see if we crash.
=> ext4ls host 0:0 invalid_d
** Can not find directory. **
./test/fs/fs-test.sh: line 161: 25786 Segmentation fault      (core dumped) $UBOOT  <<EOF

Subsequent tests will fail if U-boot crashes.

Tested on SAMA5D2_Xplained board (sama5d2_xplained_mmc_defconfig)

Looks like crash is introduced by commit:
"fa9ca8a5" fs/ext4/ext4fs.c: Free dirnode in error path of ext4fs_ls

Issue is that dirnode is not initialized, and then freed if the call
to ext4_ls fails. ext4_ls will not change the value of dirnode in this case
thus we have a crash with data abort.

I added initialization and a check for dirname being NULL.

We only call fit_conf_print from one place in the code, so mark it as

Also use a regex for matching the tarball names. Some gcc versions

all platforms.
