security/clamav: Update to 1.0.0

• Switch to use bundled TomsFastMath library. Upstream made incompatible change to bundled copy and this makes it impossible to use external one. They also dropped option to use it.
• Bump PORTREVISION of consumers as shlib version is changed.
• Note that though this is new LTS feature release security/clamav-lts stays in 0.103.x until either next regular feature release (probably 1.1.0) is released or 0.103.x reaches its EoL.
