Do not use git desribe in the release

[Anton Kochkov]

When I just run cargo install record-query it still tries to access the git. Shouldn't do that for the release version, I suppose.

error: git describe failed with status 128: fatal: 不是一个 git 仓库（或者直至挂载点 / 的任何父目录）
  --> /home/akochkov/.cargo/registry/src/github.com-1ecc6299db9ec823/record-query-1.0.1/src/lib.rs:29:31

   = note: this error originates in a macro outside of the current crate (in Nightly builds, run with -Z external-macro-backtrace for more info)

error: aborting due to previous error
