[SPARK-26094][CORE][STREAMING] createNonEcFile creates parent dirs.
## What changes were proposed in this pull request?
We explicitly avoid files with hdfs erasure coding for the streaming WAL
and for event logs, as hdfs EC does not support all relevant apis.
However, the new builder api used has different semantics -- it does not
create parent dirs, and it does not resolve relative paths. This
updates createNonEcFile to have similar semantics to the old api.
## How was this patch tested?
Ran tests with the WAL pointed at a non-existent dir, which failed before
this change. Manually tested the new function with a relative path as well.
Unit tests via jenkins.
