SCHEMA-480. Change pointcut in KijiSchema.

Change pointcut for BaseTool in KijiSchema from call to execution to
correctly capture all instances when toolMain is called.
SCHEMA-481. Fix enable/disable profiling scripts for aspectj jar.

Move the aspectj jar between $KIJI_HOME/lib/profiling and
$KIJI_HOME/lib when profiling is disabled/enabled.
Fix enable profiling's if condition.

Without this calling enable profiling twice leaves both the profiling
and non-profiling jar in ${distrodir}, which creates problems after
profiling is disabled.
Remove unchecked/rawtypes/javadoc warnings.
