HBASE-19386 Enable Arm64 unaligned support for HBase
On Arm64, java.nio.Bits.unaligned() wrongly returns false due to a JDK bug.
This causes HBase UnsafeAvailChecker wrongly returning false on Arm64.
And it slso cause FuzzyRowFilter Unit test failed.
Fix it by providing a hard-code to enbale Arm64 unaligned support.
