[PATCH nft v4 17/17] tests/shell: set TMPDIR for tests in "test-wrapper.sh"

[Thomas Haller <thaller@redhat.com>]

Various tests create additional temporary files. They really should just
use "$NFT_TEST_TESTTMPDIR" for that. However, they mostly use `mktemp`.

The scripts are supposed to cleanup those files afterwards. However,
often that does not work correctly and /tmp gets full of left over
temporary files.

Export "TMPDIR" so that they use the test-specific temporary directory.
