btrfs: fix raid-stripe-tree tests with non-experimental btrfs-progs build

When running the raid-stripe-tree tests with a btrfs-progs version that
was not configured with the experimental features, the tests fail because
they expect the dump tree commands to output the stored and calculated
checksums lines, which are enabled only for experimental builds.

Also, these lines exists only starting with btrfs-progs v5.17 (more
specifically since commit 1bb6fb896dfc ("btrfs-progs: btrfstune:
experimental, new option to switch csums")).

The tests fail like this on non-experimental btrfs-progs build:

   $ ./check btrfs/304
   FSTYP         -- btrfs
   PLATFORM      -- Linux/x86_64 debian0 6.9.0-btrfs-next-160+ #1 SMP PREEMPT_DYNAMIC Tue May 28 12:00:03 WEST 2024

So update _filter_stripe_tree() to remove the checksum lines, since we
don't care about them, and change the golden output of the tests to not
expect those lines. This way the tests work with both experimental and
non-experimental btrfs-progs builds, as well as btrfs-progs versions below
v5.17.
