pack-objects: create GIT_TEST_PACK_SPARSE

Browse source 
Create a test variable GIT_TEST_PACK_SPARSE to enable the sparse
object walk algorithm by default during the test suite. Enabling
this variable ensures coverage in many interesting cases, such as
shallow clones, partial clones, and missing objects.

GIT_TEST_PACK_SPARSE=<boolean> if enabled will default the pack-objects
builtin to use the sparse object walk. This can still be overridden by
the --no-sparse command-line argument.
GIT_TEST_PRELOAD_INDEX=<boolean> exercises the preload-index code path
by overriding the minimum number of cache entries required per thread.
