mk: fix install with tar 1.29

mk: fix install with tar 1.29

--exclude became a positional option in tar 1.29, breaking the
test app filtering in "make install", causing .map files and all test
apps to get installed in bindir. Adjust the tar arguments accordingly,
this is compatible with older versions too since they do not care about
the order.
