reproducible_build.bbclass: Enable -Wdate-time

Browse Source 
This will help identifying packages using __TIME__, __DATE__ and
__TIMESTAMP__ macros in code, its a warning from the compiler and the
packages which use -Werror will break the build with this and where they
don't we will atleast have a warning in the build logs
