[PATCH] git-tar-tree: do only basic tests in t/t5000-git-tar-tree.sh

git-tar-tree: remove tests of long path handling out of t5000-tar-tree.sh
and make test script cope with tar programs displaying file modification
date as hh:mm (newer variants show it as hh:mm:ss).

This makes the test cover only basic functionality that is expected to
be handled even by older tar programs.  Tests for long filenames (which
require pax extended headers) can be added separately.

I ran this test successfully with GNU tar 1.13, 1.14 and 1.15.1.
