[SPARK-20343][BUILD] Revert "Force Avro 1.7.7 in sbt build to resolve build
failure in SBT Hadoop 2.6 master on Jenkins"
## What changes were proposed in this pull request?
After https://github.com/apache/spark/pull/17651, it seems the build still
fails on SBT Hadoop 2.6 master.
```

I am unable to reproduce this -
https://github.com/apache/spark/pull/17477#issuecomment-294094092 and the
reviewer was too. So, this got merged as it looks the only way to verify this
is to merge it currently (as no one seems unable to reproduce this).
## How was this patch tested?
Jenkins tests.
