[PATCH 1/3] t6501: use --quiet when testing gc stderr

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <dstolee@microsoft.com>

The test script t6501-freshen-objects.sh has some tests that care
if 'git gc' has any output to stderr. This is intended to say that
no warnings occurred related to broken links. However, when we
have operations that output progress (like writing the commit-graph)
this causes the test to fail.

Use 'git gc --quiet' to avoid these progress indicators from causing
a test failure.
