Prior to this PR, Package.swift for CWebP used swift-tools-version:4.2 but it doesn't play well with the root Package.swift in swift-tools-version:5.0. This PR resolved that situation.
This PR obsoleted old fashion Modules directory for CWebP and instead, I'm going to move CWebP directory to under Sources as same as the main target. Also CWebP is now accommodated in the root Package.swift thanks to the latest API to put pkgConfig settings in .systemLibrary.
Closes #20
