build: rpm package with cargo generate-rpm

The generated rpm package has the same scope as the deb package: the stg
executable, along with man pages, completions, and vim files are installed.

The stg executable is built with --no-default-features to avoid dynamic
linkage with libbz2, libcurl, etc. in order to maximize portability.
