Add musl target for Alpine linux support (#8)

Building with `CGO_ENABLED=0` results in a binary which can run on Alpine linux (with musl libc), but it also disables SQLite support. Adding an additional target allows people to decide this tradeoff for themselves.

+## FAQ
+
+**How do I use dbmate under Alpine linux?**
+
+Alpine linux uses [musl libc](https://www.musl-libc.org/), which is incompatible with how we build SQLite support (using [cgo](https://golang.org/cmd/cgo/)). If you want Alpine linux support, and don't mind sacrificing SQLite support, please use the `dbmate-linux-musl-amd64` build found on the [releases page](https://github.com/amacneil/dbmate/releases).
