[PATCH v2] package_rpm: Add custom extension support for spec generation.

[PATCH v2] package_rpm: Add custom extension support for spec generation.

[Richard Purdie]

Add hooks to allow customisation of the rpm spec files. Since python functions
aren't visible in the data store, one variable is used to trigger the call to
a separately named function. A dummy function is not provided since this then
triggers various class ordering complexities which are best avoided.

Ultimately this will be replaced by a refactor of the code to generate the 
spec file using a python class.

This allows the tizen layer to add hooks for the security manifests for
example.
