Subject: [PATCH] [UWE] Notify internal API compatibility when installing rpm

Previously, the second and third versions haven't been used.
So, this removes the unused versions except for the wrtjs version
and newly adds {TPK_VERSION} and {INTERNAL_API_REVISION} like below:

{TPK_VERSION}.{INTERNAL_API_REVISION}.{WRTJS_VERSION}

The {TPK_VERSION} needs for deploying tpk file via app server.
The {INTERNAL_API_REVISION} needs to check API compatibility
between chromium-efl and wrtjs.

In addition, this notifies internal API version compatibility result
using the {INTERNAL_API_REVISION} when installing rpm file.
The internal API compatibility can be guaranteed only if the
{INTERNAL_API_REVISION} is same with chromium-efl.

'\033[32m' means green, '\033[31m' means red color, and '\033[m' means
end of the colors in the %pre script.
