[PATCH v2 3/7] t1010: don't create unused files

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

Builtin "git mktree" writes the the object name of the tree object built
to the standard output.  Tests 'mktree refuses to read ls-tree -r output
(1)' and 'mktree refuses to read ls-tree -r output (2)' in
"t1010-mktree.sh" redirect output of "git mktree" to a file, but don't
use its contents in assertions.

Don't redirect output of "git mktree" to file "actual" in tests that
assert that an invocation of "git mktree" must fail.

Output of "git mktree" is empty when it refuses to build a tree object.
So, alternatively, the test could assert that the output is empty.
However, there isn't a good reason for the user to expect the command to
be silent in such cases, so we shouldn't enforce it.  The user shouldn't
use the output of a failing command anyway.
