btrfs/287: filter snapshot IDs to avoid failures when using some features
When running btrfs/287 with features that create extra trees or don't
the need to create some trees, such as when using the free space tree
(default for several btrfs-progs releases now) versus when not using
it (by passing -R ^free-space-tree in MKFS_OPTIONS), the test can fail
because the IDs for the two snapshots it creates changes, and the golden
output is requiring the numeric IDs of the snapshots.
For example, when disabling the free space tree, the test fails like this:
$ MKFS_OPTIONS="-R ^free-space-tree" ./check btrfs/287

So add a filter to logical reserve calls to replace snapshot root IDs with
a logical name (snap1 and snap2).
