feat: thread checksum argument through builders

[deciduously]

This PR corrects the arguments accepted by std.build, dropping obsolete fields, and adds a checksum argument to the following interfaces which passes through to the underlying builder:

• std.autotools.build
• cmake.build
• go.build
• node.build
• rust.build

This closes #58.

Additionally, this PR includes fixes to ncurses and readline, finally allowing downstream packages to properly build against these dependencies using their pkg-config files. Closes #31.

Also includes new package definitions for lz4 and hyperfine.
