[PATCH] liblockdep: Fix unsupported 'basename -s' in run_tests.sh

[Sedat Dilek]

Here on Ubuntu/precise I have GNU/coreutils v8.13 installed
where 'basename -s' is not supported.

The result is that run_tests.sh is not done properly.

[ INSTRUCTIONS ]

$ cd $BUILD_DIR
$ LC_ALL=C make -C tools/ liblockdep
$ cd tools/lib/lockdep/

$ LC_ALL=C ./run_tests.sh
basename: invalid option -- 's'
Try `basename --help' for more information.
... timeout: failed to run command `./tests/': Permission denied
FAILED!
rm: cannot remove `tests/': Is a directory

Due to unsupported basename the tests programs are not generated
and cannot be removed.

Fix this by doing a compatible basename invocation and check for
the existence of generated tests programs.

For more details see the thread in [1] on LKML.

This patch is on top of Linux v4.6-rc1.
