Subject: [PATCH 2/2] Fix compilation errors with Avatica 1.27.0

Avatica 1.27.0 added unsigned accessor methods (getUByte, getUShort,
getUInt, getULong) to Cursor.Accessor and added a boolean signed
parameter to AvaticaSite.get(). Update ArrowFlightJdbcAccessor with
default implementations and fix the AvaticaSite.get() call site.
