cmd/fscrypt: Initial stub program and docs

This commit adds in a stub fscrypt program. The binary just tells the
time and the tests do nothing, but the Makefile will build them! This
commit also adds documentation to the README that explains how to get,
build, run, test, format, lint, and install the code.

Also note that the executable is now in the cmd/fscrypt directory. The
library implementing the core functionality will be at the root. This
is essentially point 2 of https://medium.com/@benbjohnson/structuring-applications-in-go-3b04be4ff091
