Ævar Arnfjörð Bjarmason 27472b5195 cat-file: fix a common "struct object_context" memory leak
Fix a memory leak where "cat-file" will leak the "path" member. See
e5fba602e5 (textconv: support for cat_file, 2010-06-15) for the code
that introduced the offending get_oid_with_context() call (called
get_sha1_with_context() at the time).

As a result we can mark several tests as passing with SANITIZE=leak
using "TEST_PASSES_SANITIZE_LEAK=true".

As noted in dc944b65f1 (get_sha1_with_context: dynamically allocate
oc->path, 2017-05-19) callers must free the "path" member. That same
commit added the relevant free() to this function, but we weren't
catching cases where we'd return early.
