send-pack: avoid redundant "pack-objects died with strange error"

Saying "pack-objects died with strange error" after "pack-objects died
of signal 13" seems kind of redundant.  The latter message was
introduced when the run-command API changed to report abnormal exits
on behalf of the caller (v1.6.5-rc0~86^2~5, 2009-07-04).

Similarly, after a controlled pack-objects failure (detectable as a
normal exit with nonzero status), a "died with strange error" message
would be redundant next to the message from pack-objects itself.

So leave off the "strange error" messages.

The result should look something like this:

	$ git push sf master
	Counting objects: 21542, done.
	Compressing objects: 100% (4179/4179), done.
	fatal: Unable to create temporary file: Permission denied
	error: pack-objects died of signal 13
	error: failed to push some refs to 'ssh://sf.net/gitroot/project/project'
	$

Or in the "controlled exit" case (contrived example):

	[...]
	fatal: delta size changed
	error: failed to push some refs to 'ssh://example.com/foo/bar'
	$
