[PATCH v3 2/7] t1006: assert error output of cat-file

[Andrei Rybak <rybak.a.v@gmail.com>]

Test "cat-file $arg1 $arg2 error on missing full OID" in
t1006-cat-file.sh compares files "expect.err" and "err.actual" to assert
the expected error output of "git cat-file".  A similar test in the same
file named "cat-file $arg1 $arg2 error on missing short OID" also
creates these two files, but doesn't use them in assertions.

Assert error output of "git cat-file" in test "cat-file $arg1 $arg2
error on missing short OID" of t1006-cat-file.sh to improve test
coverage.
