[PATCH mtd-utils v3] tests: add test_DATA to EXTRA_DIST

[Michael Olbrich]

Otherwise, the test files are missin in the tarball and building fails
with:

make[1]: *** No rule to make target 'tests/ubifs_tools-tests/images/good.gz', needed by 'all-am'.  Stop.

unless --without-tests is uses.

Changes in v2:
 - introduce a new variable for the test files
 - extend EXTRA_DIST in tests/ubifs_tools-tests/Makemodule.am instead of
   the toplevel Makefile.am

Changes in v3:
 - added missing whitespace
