`zig_binary|library|test` should support a Zig binary with library dependencies (`.a`, `.so`)

[aherrmann]

Zig has two different ways to link against pre-built objects or libraries. Either, by passing the corresponding files on the command-line, in which case they are passed as file paths to the underlying linker, or by passing -l type flags, in which case they are looked up in the library search paths and either resolved to files or forwarded as -l type flags to the underlying linker.
