[PATCH] btrfs-progs: misc-test/034: Avoid debug log populating stdout

[Qu Wenruo]

When running misc-test/034, we got unexpected log output:
      [TEST/misc]   033-filename-length-limit
      [TEST/misc]   034-metadata-uuid
  Checking btrfstune logic
  Checking dump-super output
  Checking output after fsid change
  Checking for incompat textual representation
  Checking setting fsid back to original
  Testing btrfs-image restore

This is caused by commit 2570cff076b1 ("btrfs-progs: test: cleanup 
misc-tests/034")
which uses _log facility which also populates stdout.

Revert to echo "$*" >> "$RESULTS" to remove the noise.
