cmd: Simplify "fscrypt --version" output (#207)

There's no need to include the build time, author, and copyright info
in the output of "fscrypt --version". This information is:

  - Overly complex (the current string is hard to parse)
  - Inaccurate (there are other authors than just me)
  - Unnecessary (the Apache 2 license is for Source Code)
  - Makes reproducible builds impossible

The default version string is just fine.
