btrfs-progs: rework testsuite export

Move the testsuite to tests/ and make the tarball generation more
deterministic. As there could be many random temporary files left in the
test directories, we can't just copy them. Use 'git ls-tree' to
filter just what we want, this needs a slight extension of the file list
specification.
