Followup to r1567717
Remove several other uses of compile.optimize property,
the optimize flag is noop for current versions of javac (as Ant manual says).

Provide explicit default for compile.deprecation property.
It controls whether -deprecation flag (a synonym for -Xlint:deprecation) is passed to javac.
No functional change here, as String->boolean conversion in Ant treats any value except of "on", "true", "yes" as false (Project.toBoolean()).
