Tools: Tune: SRC: Update generator to produce similar as edited

This patch makes to SRC coefficients tables generator same changes
as done in recent git commits.

commit 88fdb10 ("audio: src: rename sample rate converter
coefficient folder name") moved coefficients files location to
src/audio/src/coefs.

commit 90fef5a ("src_lite: add module") removed include of
src.h from upper level due to another src-lite version.

'commit 7f4e6ae ("src: make coefficients constant")
added const to struct src_stage.
