xbps-src: multiple performance improvements

- use xbps-checkvers(1) to resolve dependencies.
- all dependencies are installed at once for the host and target.
- the show-build-deps target is now much faster.
- the update-bulk/show-repo-updates targets are now much faster.
- the update-sys/show-sys-updates targets are now much faster.
- the bootstrap target now works on musl hosts.
- simplified some loops.
- use cut(1) rather than awk(1) where applicable.
- multiple random changes to improve performance.
