Fix #148 (#149)

* check minimal versions with cargo-minimal-versions

* move benchmark to last step of CI

* Only allow patch updates to the sys crate

Use the `~` version specifier, which only allows changes in the last digit of
the version. Additionally, force use of version `4.1.1`+, as `4.1.0`
incorrectly claimed the library version in the c code

* correct minimal cc version
