Resolve baseline future

My commit yesterday to fix --no-remove-copy-calls/initCopy with extern structs
resolved this future.  Since the future was a copy of
test/extern/bradc/structs/externFloat4calls.someFields.chpl, I am removing the
future in its entirety and allowing the someFields test to run with --baseline
again.
