Do not print timestamp in python-Cheeta by setting an argument.

- PROBLEM
We use OBS to build packages in Tizen.
There is a mechanism not to rebuild if the result binary is the same.
For example, there is a dependency graph: A->B->C.
If A is modified, B would be built.
If the result RPM of B is not changed, OBS does not trigger a build of C.
To effectively use this mechanism, each packages make sure that
the result binary should be the same if the input source is the same.

This package uses python-Cheeta package.
This python-Cheeta package prints code generation time like below:

[   49s] -__CHEETAH_genTime__ = 1471828672.098387
[   49s] -__CHEETAH_genTimestamp__ = 'Mon Aug 22 01:17:52 2016'
[   49s] +__CHEETAH_genTime__ = 1471844774.503833
[   49s] +__CHEETAH_genTimestamp__ = 'Mon Aug 22 05:46:14 2016

This timelog is not printed if we insert settings parameter:

$(CHEETAH) compile --settings='useStackFrames=False,addTimestampsToCompilerOutput=False' $<
