btrfs/017: support all possible page sizes

Browse Source 
Currently this test fails on 2 situations:

1) The scratch device supports trim/discard. In this case any modern
   version of mkfs.btrfs outputs a message (to stderr) informing that
   a trim is performed, which the golden output doesn't expect:

   btrfs/017	 - output mismatch (see /git/xfstests/results//btrfs/017.out.bad)

        (Run 'diff -u tests/btrfs/017.out /git/xfstests/results//btrfs/017.out.bad'  to see the entire diff)

    So like others tests do, just redirect mkfs' standard error.

2) On platforms with a page size greater than 4Kb. At the moment btrfs
   doesn't support a node/leaf size smaller than the page size, but it
   supports a larger one. So use the max supported node size (64Kb) so
   that the test runs on any platform currently supported by Linux.
