hash-object: fix a trivial leak in --path
Fix a memory leak that happened when the --path option was
provided. This leak has been with us ever since the option was added
in 39702431500 (add --path option to git hash-object, 2008-08-03).
We can now mark "t1007-hash-object.sh" as passing when git is compiled
with SANITIZE=leak. It'll now run in the the
"GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI
target).
