fix(build): fix spec file paths and Windows CRLF in VERSION

- OmniDB-lin.spec was nested in OmniDB/OmniDB/ instead of OmniDB/
- omnidb-win.spec had wrong casing (OmniDB-win.spec expected by Makefile)
- VERSION read with tr -d '\n' left \r on Windows CRLF checkouts,
  breaking sed commands; changed to tr -d '\r\n'
